ANALYSIS OF TM NONLINEAR OPTICAL WAVEGUIDE SENSORS

Rahrovan Zahra, Shahmirzaee Hossein

Abstract: In this paper, we offer an analytical theory to study three-layer slab waveguide for sensor applications. Proposed sensor consists of a linear thin dielectric film that is surrounded by a nonlinear asymmetric environment. We consider polarized waves ???? and nonlinear environments as of Kerr type. We also investigate sensor sensitivity for maximum mood, nonlinear sensors have a higher sensitivity than linear sensors. This sensitivity in nonlinear sensors can increase up to 10/072 % compared to linear sensors.

Keywords: Sensitivity, Thin dielectric film, Sensor fiber.
