KTiOPO4:(KTP): A New And Superior Electrooptic Material For Guided Wave Optics

Electrooptic modulation is the changing of the phase or amplitude of an optical beam by an applied electric field. This phenomenon is inherently nonlinear and can only be observed in crystals that do not have an inversion symmetry. The modulation, when effected in a waveguide, is the foundation of many guided wave optical devices, such as: Mach-tender interferometers, channel switches and directional couplers, etc. which are particularly useful for fiber optics communication)
