Paper Abstract

We present theoretical and experimental investigations of integrated optical 3x3-couplers on LiNb0,. Since this system hasn't reached much attention as yet, we made extensive numerical calculations on the basis of coupled mode theory and prepared samples with a wide range of design parameters for use at 820 nm wavelength. Results of various optical measurements are compared to theoretical data. Our investigations show that experimental values agree quite well with theoretical calculations. Coupling constants are determined and different interesting applications are examined. Successful use of a 3x3-coupler in a fiber optic Mach Zehnder interferometric sensor with passive signal evaluation is demonstrated.
