The mood in the Dutch and the European integrated photonics scene has been changing. After years of confidently touting a technological lead, these days figureheads issue words of warning: if we don’t act soon, the US and China may run off with the loot. Twan Korthorst, along with many partners, is taking a step forward: "I’m convinced silicon nitride is a great niche catering to a unique set of applications. Or rather: a niche of a niche, because we really need to start talking about integrated photonics as a part of the semiconductor industry. Integrated photonics and electronics are natural allies rather than competitors, after all.” Read this in-depth interview with Twan Korthorst: https://lnkd.in/e6UtuWN4 #integratedphotonics #photonics #neworigin

Edinburgh Instruments Map of the Month – Gallium Nitride Scientists are developing new materials to create smaller, more powerful electronics. One promising candidate is gallium nitride (GaN)! ✨ This amazing material is already used in blue LEDs, but it could also replace silicon in future devices. Here's why: ✨Wide bandgap: Makes GaN super efficient, especially at high temperatures ✨Tiny and tough: Perfect for packing a lot of power into small spaces However, GaN devices need to be perfect to work well. Luckily, we have imaging techniques like photoluminescence microscopy to check for any imperfections! Want to learn more about how GaN LEDs work?
