Single mode ridge waveguide using hybrid organic-inorganic sol-gel

Optical waveguides are structures that confine and direct optical signals in a region of higher effective index than its surrounding media. For integrated optics and photonic applications, it is often of importance to prepare waveguides in the form of thin film and channel structures. Hybrid sol-gel...
