Robust Geometries for Second-Harmonic-Generation in Microrings Exhibiting a 4-Bar Symmetry
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 on the quasi-phase matching condition, which in tu...
