Fabrication of MgO:LiNbO₃ Domain Inverted Structures with Short Period and Application to Electro-Optic Bragg Deflection Modulator

Abstract

We fabricated high-quality domain-inverted MgO: LiNbO₃ structures with 3.0 and 2.0 μm periods using applying votage to the corrugation electrode. We found that keeping the crystal temperature at 150^°C for 12 hours before applying voltage was effective for obtaining good uniformity. We also demonstrated an application of the structures with 3.0 μm period to electro-optic Bragg deflection modulator for the first time.
