Second-harmonic generation using [Image: see text]-quasi-phasematching in a GaAs whispering-gallery-mode microcavity
The [Image: see text] crystal symmetry in materials such as GaAs can enable quasi-phasematching for efficient optical frequency conversion without poling, twinning or other engineered domain inversions. [Image: see text] symmetry means that a 90° rotation is equivalent to a crystallographic inversio...
