ساختارهای سیلیکونی بسیار نازک می توانند نور میانی IR را در میلیاردم ثانیه تنظیم کنند

Ultrathin silicon structures can tune mid-IR light in billionths of a second

Light in the mid-infrared (mid-IR) portion of the electromagnetic spectrum plays a key role in modern sensing. Because molecules interact with this kind of light in specific ways, researchers use technologies like mid-IR spectroscopy to identify biological materials, drugs and pollutants. Mid-IR light can also serve as a carrier of information in free-space optical communications, where data are transmitted through…
