Thermal analysis of thermooptic device using planar optical waveguide structures is performed by using implicit finite difference method. Isothermal profiles of the medium having the core and cladding are shown from the computation results. We have proposed two new structures where lower heating power is required when compared to that of the conventional structure. A compromise between heating power...
We have studied mask based process for the microfabrication of polymeric (IXn) branching waveguides both theoretically and experimentaly. The simulation is based on the two-dimensional finite-difference beam propagation method (FDBPM) for the design of the waveguiding devices. The transmission efficiency of truncated structural Y-branch (TSYB) for wide angle (IX2) splitter with a full branching angle...
