Microring resonators made of materials with a zinc-blend or diamond lattice allow exploiting their 4-bar symmetry to achieve quasi-phase matching condition for second-order optical nonlinearities. However, fabrication tolerances impose severe limits

Ultrahigh-quality (Q) factor optical micro-resonators with very long photon storage time are important in the aim of integrating optical functions such as filters, tunable delay lines for microwave-photonics or highly sensitive sensor applications. T

GaP is a promising candidate for the development of highly integrated photonic functions on silicon, because of its quasi lattice-matching with Si and its interesting χ(2) non-linear properties. We here present the realization of GaP-based microdisk
