Abstract :
Nano-second speed optical switches and filters fabricated in epitaxially grown (Pb, La)(Zr, La)O3 (PLZT) waveguides are reported. The optical switches including 1×2, 2×2, and 1×16 ports have switching time less than 10 ns and the AWG based 8×1 wavelength filter has 15 ns switching time. A PLZT buried waveguide is successfully developed to minimize insertion loss and polarization dependence in the optical switches.
