Abstract

Over the last several years, there has been a growing interest in the use of integrated otpic (IO) components and circuits in fiber optic sensor systems. Initial work on integrated optic sensors focused on the use of IO chips themselves as sensors for temperature and pressure. More recently, integrated optics has generally been employed to perform key optical signal processing functions in a fiber sensor or as a signal transduction mechanism for an electrooptic sensor system. This paper will focus on these latter applications. Emphasis will be on chips for fiber optic gyroscopes, laser vibration sensors, and electromagnetic field sensors. In many cases, recent advances in chip technology such as annealed- proton-exchange waveguides in LiNbO₃ and LiTaO₃, has enhanced circuit performance and manufacturability, making IO technology a viable choice for the fiber sensor designer.
