Abstract

A lithium niobate integrated-optics power-splitter waveguide with electro-optic phase shifters is used in a heterodyne interferometer with a laser diode source emitting at 830 nm. An acousto-optic Bragg cell is used for frequency shifting. Multichannel 100-MHz signals with individually controlled phase information are generated by mixing the optically phase-shifted reference beams and frequency-shifted Bragg cell signal in fiber-optic receivers.
