Abstract
An interferometer temperature sensor based on a semi-asymmetric X junction made of four single-mode Ti:LiNbO3 channel waveguides is described. For a fixed path length difference, the X-cut configuration exhibits a thermal sensibility greater than that of Z-cut interferometer. The X-cut version is found to be superior for both thermal stability and sensitivity.
