Researchers from MIT’s Research Laboratory of Electronic have designed an optical filter on a chip that can process optical signals from across an extremely wide spectrum of light at once.
“This new filter takes an extremely broad range of wavelengths within its bandwidth as input and efficiently separates it into two output signals, regardless of exactly how wide or at what wavelength the input is. That capability didn’t before in integrated optics,” says Emir Salih Magden, a former PhD student in MIT’s Department of Electrical Engineering and Computer Science (EECS) and first author on a paper describing the filters published today in Nature Communications.
Potential applications include fiber-to-the-home installations.
