Abstract

Characteristics of waveguides with periodically domain-inverted regions in LiNbO3 and LiTaO3 for quasi-phase-matched (QPM) second harmonic generation are investigated. The domain-inverted regions in LiNbO3 are formed by heat treatment using selective SiO2 mask and those in LiTaO3 are formed by heat ...
