SiC photonics resonator has Q=160,000 for CMOS

Silicon carbide can be used to add telecoms-wavelength (1.55μm) emission to CMOS, according to researchers at MIT and Singapore University of Technology (SUTD), who demonstrated an amorphous SiC ring resonator with a Q of 1.6×105, claimed to be the highest quality factor achieved in a SiC micro-ring resonator. “We are able to show one order of ...
