Abstract

High power blue light generated by quasi phase matched (QPM) second harmonic generation (SHG) techniques is very attractive for high density optical storage. KTiOPO/sub 4/ (abbreviated as KTP) is one of the most important materials used in QPM SHG. Since 1987 many kinds of waveguides and devices have been demonstrated in KTP substrates. However there still remains some technique problems, for example, the control of the duty cycle of the segmented waveguides as well as cracking of the waveguides. On the other hand the photolithography process used for fabrication of KTP segmented waveguides has not been reported. In this paper we report on the experimental results of segmented optical waveguides fabricated in KTP substrates.
