Silicon-based monolithic optical frequency comb source

Opt Express. 2011 Jul 18;19(15):14233-9. doi: 10.1364/OE.19.014233.


We demonstrate the generation of broad-bandwidth optical frequency combs from a CMOS-compatible integrated microresonator. We characterize the comb quality using a novel self-referencing method and verify that the comb line frequencies are equidistant over a bandwidth of 115 nm (14.5 THz), which is nearly an order of magnitude larger than previous measurements.
