Abstract
Quasi phase matching (QPM) crystals using GaN were designed and fabricated for the development of ultraviolet lasers. GaN-QPM crystals were fabricated by the double polarity selective area growth (DP-SAG). As a result of optical measurement using such fabricated crystals, second harmonic generation (SHG) due to phase matching was confirmed.
