摘要:
A novel test setup for making three-prism or out-of-plane scattering loss measurements for thin-film optical waveguides is described. The test structure is automated and provides quick, convenient and repeatable measurements. The setup is relatively easy to fabricate and employs several unique features which improve the accuracy and repeatability of the measurements including real-time coupling force monitoring.
