Abstract
Using a 10.5 GHz resonant electro-optic modulator placed inside a resonant optical cavity, we have generated an optical frequency comb with a span wider than 3 THz. The optical resonator consists of three mirrors, with the output coupler being a thin Fabry-Perot cavity with a free spectral range of 2 THz and finesse of 400. Turning this filter cavity onto resonance with a particular high-order sideband allows as to efficiently couple out the desired sideband power from the comb generator, while keeping all others inside for the continued comb generation. This spectrally pure output light was then heterodyne detected by another laser with a frequency offset on the order of one THz.Citation
