| Research Abstract |
A silicon wire waveguide with a triangular cross section can rotate the polarization with a short device length of a few micrometers. The operation mechanism is theoretically explained together with an experimental demonstration at a microwave frequency. A novel implicit finite-difference time-domain method has been developed, which allows us to evaluate the frequency response of various optical devices at a one-time solution. The method is applied to the design of a waveguide-type sensor.
