Poled glass optical communication devices

A review of electro-optic and nonlinear optical devices based on poled glass will be presented, including recent developments and potential applications. Optical glass waveguides play a key role in information technology because of their excellent optical properties, including low loss, and low fabrication costs. The availability of low-loss silica fibres has led to a revolution in optical communications and low-loss silica waveguides are used to produce a variety of optical integrated elements, such as optical splitters, filters and routers. A second-order nonlinearity poled optical glass telecommunications device would be advantageous for frequency conversion and switching applications
