Abstract

Doubly resonant microcavities can be used to enhance optical nonlinearities. We propose a coupled modes analysis of second-harmonic generation in cylindrical whispering gallery mode III-V microresonators. We show that microdisks can be used to obtain the quasi-phase-matching condition and that by engineering their refractive index it is possible to optimize the effective second order nonlinear polarization by maximizing the fundamental and second-harmonic mode overlap. In a second part we show that the use of side-coupled integrated spaced sequence of resonators (SCISSOR) can lead to an adaptation of the Fresnel phase-matching to the case of highly confining waveguides.
