Monolithic, unetched BTO strip waveguides

Background Electro-optic technology relies on the operation of systems/devices through the propagation and interaction of light with various tailored/optically active materials. Typical electro-optical devices are designed to modulate the properties of a light wave (e.g., phase, polarization, amplitude, frequency, direction of propagation) and include...
