Abstract

Outcoupling of guided modes via a high index liquid acting as movable coupling prism allows for the direct detection of guided power versus propagation distance without the drawbacks of the common two prism method. We present a setup based on this principle which is capable of performing precise loss measurements of plane and strip waveguides. Furthermore, excess losses of devices caused by local defects, bending etc. can be distinguished from the fundamental loss background.
