Microstructural and optical properties of [Ba.sub.0.5][Sr.sub.0.5]Ti[O.sub.3] thin film deposited by pulsed laser deposition for low loss waveguide applications

Numerous techniques are used to explain the microstructural, surface morphology and the optical properties of barium strontium titanate ([Ba.sub.0.5][Sr.sub.0.5Ti[O.sub.3] or BST) films deposited by the pulsed laser deposition technique. The films explained are found to be extremely helpful, as they can be widely used for several low loss waveguide, as well as different advanced optical integrated systems.
