We are happy to announce that new research on an improved coupled-mode theory for high-index-contrast photonic platforms has been published on Physical Review A. 

We have recently published our new research, conducted by Xiyuan, on the development of microresonator optical parametric oscillators (OPOs) in which a near-infrared pump laser creates any one of a set of distinct colors.

Xiyuan recently published his newest results on frequency engineering of microring resonators through inner sidewall modulation of the resonator.

This approach enables selectively frequency splitting of several resonances that can be arbitrary selected. Such research opens the door to further engineering of frequency/phase matching for ultra-efficient non-linear processes such as four-wave mixing. Have a look at his paper in the latest issue of Photonics Research!  

Our paper, in collaboration with Prof. John Bowers' group from University of California at Santa Barbara, shows the generation of a Dissipative Kerr Soliton (DKS) in a III-V platform, namely AlGaAs-on-insulator, thanks to the quenching of the thermo-refractive effect at cryogenic temperaure.
