Optical frequency comb spectroscopy.

Optical frequency combs offer enormous potential in the detection and control of atoms and molecules by combining their vast spectral coverage with the extremely high spectral resolution of each individual comb component. Sensitive and multiplexed trace gas detection via cavity-enhanced direct frequency comb spectroscopy has been demonstrated for various molecules and applications; however, pre...

Optical frequency comb generation from aluminum nitride microring resonator.

Aluminum nitride (AlN) is an appealing nonlinear optical material for on-chip wavelength conversion. Here we report optical frequency comb generation from high-quality-factor AlN microring resonators integrated on silicon substrates. By engineering the waveguide structure to achieve near-zero dispersion at telecommunication wavelengths and optimizing the phase matching for four-wave mixing, fre...

Dual-pump frequency comb generation in normally dispersive optical fibers

We show that tunable frequency combs can be generated by launching two continuous-wave pumps at slightly different wavelengths into a normally dispersive optical fiber. The dual-pump configuration allows the tuning of comb spacing into the terahertz regime. Different pump powers and frequency separations are explored numerically to determine the effect of the input parameters on frequency comb ...
