Abstract
Electro-optic waveguide switches and modulators, using LiNbO3 crystal, which are the key components in the future optical communication systems, are reviwed. The advantages of the Titanium diffused waveguides include, no degradation of electro-optic effect, low propagation loss, low fiber-coupling loss and ease of fabricaiton. The operating principles and general design considerations of directional couplers switches, cross waveguide switches and balanced-bridge type switches are briefly reviewed. The design and development considerations of a simple polarization independent switch with low drive voltage for OTDR applications, is described. Optical matrix switches for photonic switching systems and optical modulators for high speed optical communication systems are also briefly reviewed.
