Paper Abstract

Modal properties of silica waveguides are presented along with their results on single mode operation, spot-size variations, confinement factor and, modal field profiles for different index contrast value between the core and the claddings. Both dominat and non-dominat field profiles and their transverse variations are also shown. Numerically simulated results also suggests that by using the MM-based design a very compact optical power splitter, of the order of 500 μm in length, can be designed, which is much shorter than conventional directional coupler or Y-junction-based designs.
