Transparent electro-optic ceramics and devices

This paper summarizes the material synthesis and properties of transparent electro-optic ceramics, namely OptoCeramic®, including PLZT and PMN-PT. Material structure, dielectric, optical and electro-optic properties are discussed. OptoCeramic materials feature in high E-O effect, low optical loss, broad transmission wavelength range, ceramic ruggedness, and low cost. A variety of devices made from OptoCeramic materials are discussed, including variable optical attenuators, polarization controllers, sinusoidal filters, dynamic gain flattening filters, tunable optical filters, and Q-switches.
