WebJan 1, 2024 · Another emerging comb source, the electro-optic modulator (EOM) comb, operates by combining intensity modulations of a single CW laser with two EOMs, inserted in branched optical paths, to generate mutually coherent dual combs. The common-mode noise cancellation guarantees a comb-resolved resolution without the need for active … WebJan 27, 2024 · In addition, optical frequency comb harmonic generation [139] has been observed. These breakthroughs have not been possible in SOI at telecom wavelengths because of its low FOM. By contrast, only recently has an optical parametric oscillator, or frequency comb source, been directly demonstrated in a silicon ring-resonator [133].
