Abstract

Proton exchanged LiNbO3 devices are used advantageously for fiber optical sensors because of the high optical damage threshold, extremely high polarization maintenance, and flexibility of waveguide parameters as a consequence of different annealing procedures. For a fiber optical gyroscope operating at a wavelength of 850 nm, a device has been developed integrating the functions of space filter, polarizer, splitter, and modulators on a single chip. This device has been fabricated by annealed proton exchange (LiNbO3:APE); the fabrication technique is described. The optical parameters of the chip and the results
