I just bought a watch wider for my wife's rolex's. Haven't nailed the setting yet, some run faster than others, especially when nobody is around so I do them by hand, lol. The lights are crazy, cool, but who cares, that is one thing that we don't talk about in a public setting. It is not like a new leaf blower.
Don't let them get to you.
Thanks,
Real people doing real things, that is all that matters. Message boards are becoming like the old house phones. Useless nonsense junk rubbish.

Plasmonic modulators might become commercially viable at scale within the next 5-10 years. Vaporwave can't make it that far without HEAVY dilution. The best thing that could happen here is a buyout from a large deep pocket player who can support the mission for another decade in the hopes of commercializing the technology.
Polariton is NOTHING to get excited about at this point.
There are several key challenges in scaling up plasmonic modulators for commercial viability:
1. Optical attenuation: Plasmonic geometries suffer from fundamental optical attenuation due to Ohmic losses of electrons in the metal, which limits their performance and efficiency.
2. Thermal effects: Managing thermal effects in plasmonic systems is a major challenge, as they can impact the performance and reliability of the devices.
3. Integration with existing systems: There is a need to improve the integration of plasmonic components with current photonic and electronic systems, particularly due to the size mismatch between micrometer-scale photonic components and nanometer-scale electronic components.
4. Manufacturing and process variation: Plasmonic devices are susceptible to manufacturing-induced variability, which can affect their performance and require additional tuning mechanisms.
5. Energy efficiency: While plasmonic modulators offer potential for energy-efficient high-speed modulation, further improvements are needed to compete with other technologies.
6. Long-term reliability: Ensuring the long-term reliability of plasmonic modulators, especially in harsh environments or at cryogenic temperatures, remains a challenge.
7. Cost-effective manufacturing: Scaling up production while maintaining performance and cost-effectiveness is a significant hurdle for commercial viability.
8. Bandwidth limitations: Balancing the trade-off between high bandwidth and other performance factors, such as Q-factor and temperature sensitivity, is an ongoing challenge.
Addressing these challenges will be crucial for the widespread adoption and commercial scaling of plasmonic modulators in various applications, including high-speed data transmission and quantum computing.
Remember, just because R&D experiments work in the lab in one off devices, doesn't make it commercially viable. Don't be fooled by fancy PR's of those talking their own book and posturing for further research dollars.

Plasmonic Modulators Can Break the Wireless Terahertz Barrier. The tech could find a home in 6G networks and AI data centers
https://spectrum.ieee.org/terahertz-waves-2671362433
Modern telecommunications infrastructure relies on a broad range of technologies. But ironically, some of these technologies can’t readily communicate with each other.
The electrical signals used for wireless communications, for example, can’t just be shoved into the fiber-optic infrastructure that forms the backbone of modern networks. Instead, they must be first converted to light (and then back again). This important task is performed by a network component called an electro-optic (EO) modulator.
“All information that you have is in the electrical world, but once it leaves your house, it goes into fiber. So, you need components that can encode from the electrical to the optical world signals at enormous speed. That’s where the modulator comes in,” says Juerg Leuthold, the head of the Department of Information Technology and Electrical Engineering at ETH Zurich, the Swiss Federal Institute of Technology of Zurich.
Telecommunications providers hope that next-generation 6G networks will deliver wireless speeds up to a terabit per second, and possibly beyond. However, these fast wireless networks still need to connect with wired fiber-optic infrastructure. That means electro-optic modulators need an upgrade—or else they risk becoming a bottleneck.
Plasmonic EO Modulator Breakthrough
Leuthold is coauthor of a paper recently published by researchers at ETH Zurich and Polariton Technologies in Switzerland that demonstrated a plasmonic EO modulator capable of frequencies up to 1.14 terahertz. It also provided 3-decibel EO bandwidth at a frequency of 997 gigahertz. Put more simply, the modulator can process signals up to nearly a terahertz before significant signal degradation occurs.
That’s a big leap from the modulators commonly in use today. Most are based on materials like lithium niobate (LiNbO3), indium gallium arsenide (InGaAs) and, more recently, silicon. Modulators using these materials typically have a frequency response that degrades when frequencies reach 60 to 100 GHz. The plasmonic EO modulator achieved a roughly tenfold improvement.
As you might expect, a plasmonic EO modulator works a bit differently from its predecessors.
Conventional modulators often rely on the Pockels effect, which describes how an applied electric field can change the refractive index of a nonlinear crystal material. The changes in the refractive index alter the light that passes through the material, making it possible to write an electrical signal into an optical signal.
Plasmonic modulators still use the Pockels effect, but the light directed into the modulator is transformed. “We take the photons, a red photon, convert it into a plasmon, and the plasmon propagates along the surface of a metal,” explains Leuthold.
Plasmons are the quanta of electron oscillations in a metal, and they have useful properties. When coupled with electromagnetic fields, they form surface plasmons that can concentrate energy into volumes smaller than the wavelength of light. These plasmonic waves propagate across metal structures.
A plasmonic modulator takes advantage of this by cutting tiny slots just 100 nanometers wide into gold. The slots are filled with an organic electro-optic material, which can change the refractive index of the light. Within these slots, the optical signal (carried by plasmons) and electrical signal interact, writing the electrical signal into the optical signal.
Because the slots are so small, the electrical field is enhanced by up to 35,000 times. That allows a far stronger interaction between the electrical and optical signals.
Commercializing Plasmonic Modulators
The demonstration of a plasmonic EO modulator that achieves frequencies up to 1 THz is the latest in a decade-long string of plasmonic modulator innovations out of ETH Zurich.
ETH Zurich researchers, including Leuthold, published a paper on the use of plasmons for electrical to optical conversation in 2015 and, at the time, predicted it could allow frequencies up to 1 THz. They’ve now shown that possibility to be a reality.
Plasmonic modulators are being commercialized by Polariton. Spun out of ETH Zurich in 2019, Polariton was cofounded by three former Ph.D. students who contributed to prior research: Wolfgang Heni, Benedikt Baeuerle, and Claudia Hoessbacher.
Polariton currently offers silicon and plasmonic EO modulators capable of up to 145 GHz. Baeuerle says the company has “engineering samples available in small quantities” capable of up to 1 THz.
Modulators like this will be required if next-generation 6G telecommunications networks hope to live up to lofty promises.
While no standards have been set for 6G networks, they’re expected to use terahertz frequencies to deliver data rates that may soar beyond one terabit. Traditional EO modulators (which, as mentioned, top off around 100 GHz) would become a pinch point if these high-speed networks were put into practice.
The technology also has a place in AI data centers. Data centers built for AI typically have clusters of GPUs connected by an internal fiber-optic network. And, just like any other fiber-optic network, an electro-optical modulator is required to convert electrical signals to light (or back). Polariton produces both modulators and transceivers (which convert signals in both directions).
“Our electro-opticmodulator is a solution for the next generation of transceivers for data centers and AI cluster that require high-speed and compact integration,” says Baeuerle. He notes that high-speed transceivers, including “next-generation” 3.2T (terabits per second) transceivers, will push electro-optical bandwidth to new heights.
Data rates this high might seem outlandish, and to be clear, 6G continues to face significant hurdles. Even so, advancements like plasmonic EO modulators and transceivers set the foundations required for faster, more reliable telecommunications.
“We are prepared for the next generation in the wireless world,” says Leuthold.

What is positive divergence in technical analysis and is it a reliable indicator?
https://gemini.google.com/app/48267711dd5515d3
Positive divergence in technical analysis occurs when the price of an asset makes lower lows, but a technical indicator (like RSI, MACD, or Stochastics) makes higher lows. This suggests that the selling pressure is weakening, and there's a potential for an upward price reversal. It's often seen as a bullish signal.
Here's a breakdown:
Price Action: The price of the asset is trending downwards, forming a series of lower lows.
Indicator: A chosen technical indicator shows increasing momentum, forming higher lows despite the falling price. This indicates that the downward trend might be losing strength, and buyers could be stepping in.
Is it a reliable indicator?
Positive divergence can be a valuable tool for traders, but it's not a completely reliable indicator on its own. Like any technical analysis tool, it's most effective when used in conjunction with other forms of analysis and confirmation signals.
Factors to consider regarding its reliability:
Confirmation: It's often best to wait for confirmation of the potential reversal before taking a trade. This could come in the form of a bullish candlestick pattern, a break above a trendline, or an increase in volume.
Timeframe: The significance of divergence can vary depending on the timeframe being analyzed. Divergence on longer timeframes (e.g., daily or weekly charts) is generally considered more significant than divergence on shorter timeframes (e.g., hourly charts).
Indicator Choice: Different indicators may provide different signals. Some traders prefer certain indicators for identifying divergence over others.
Market Conditions: Divergence signals may be less reliable in highly volatile or sideways markets.
False Signals: Like any technical indicator, positive divergence can sometimes generate false signals. The price might continue to fall even after a bullish divergence appears.
In summary:
Positive divergence is a potentially bullish signal indicating a weakening downtrend. While it can be a useful tool for identifying potential buying opportunities, it should be used with caution and in conjunction with other technical analysis methods to increase the probability of a successful trade. No single indicator should be relied upon exclusively for trading decisions.
