Abstract

In this paper, design, fabrication, measurement, and performance charcteristics of the titanium-indiffused proton-exchanged microlenses, microlens arrays, and their combinations in LiNbO₃ with emphasis on the most recent results are detailed first. Utilization of such TIPE microlenses for acoustooptic Bragg diffraction in a LiNbO₃ channel–planar composite waveguide and realization of an integrated AO Bragg modulator module in a substrate size of 0.2 × 1.0 × 2.0 cm are then described. Some of the potential applications of such an integrated optic module together with the preliminary results of a simple experiment on matrix–vector multiplication are also presented.
