Simple Single-Section Diode Frequency Combs

Matthew. W. Day, Mark Dong, Bradley C. Smith +5

Frequency combs, broadband light sources whose spectra consist of coherent, discrete modes, have become essential in many fields. Miniaturizing frequency combs would be a significa…

Quantum-Well Laser Diodes for Frequency Comb Spectroscopy

Mark Dong, Matthew W. Day, Herbert G. Winful +1

We demonstrate simple optical frequency combs based on semiconductor quantum well laser diodes. The frequency comb spectrum can be tailored by choice of material properties and qua…

A New Approach to Cascaded Stimulated Brillouin Scattering

Mark Dong, Herbert Graves Winful

We present a novel approach to cascaded stimulated Brillouin scattering and frequency comb generation in which the multitude of interacting pump, Stokes, and anti-Stokes optical fi…
