Abstract
Optical temperature sensors accessible by optical fibers are being developed for applications requiring high sensitivity and immunity to electrical noise. A variety of devices have previously been reported,1 but each has either a narrow operating range or low resolution. We report here an Integrated optical temperature sensor utilizing waveguide interferometers in LiNbO3 with a projected range and resolution of >300°C and 5 ×10−2°Crespectively. This is the first application of integrated optics to temperature sensing and is a significant improvement over previous devices.
