Measurement of Small Birefringence and Loss in a Nonlinear Single-mode Waveguide



Daniel Rogers, Charles W. Clark, Christopher Richardson, Julius Goldhar


We design and fabricate a birefringent semiconductor waveguide for application to nonlinear photonics, demonstrating that it is possible to engineer a small birefringence into such a device using multiple core layers. We also demonstrate a simple technique to accurately determine small waveguide birefringence using a di erential measurement, present useful methods for coupling light into and out of the device, and make estimates of coupling and linear device losses.
