Design and analysis of Mach-Zehnder interferometer sensors based on dual strip antiresonant reflecting optical waveguide structures

Abstract

Mach-Zehnder interferometer sensors based on dual strip antiresonant reflecting optical waveguide (ARROW) structures are proposed. By adjusting the degree of structural symmetry to control the coupling behavior of the dual strip ARROW, an interferometric sensor without any bending structures can be realized. Operating principles and an analysis of the device are discussed in detail. (c) 2005 Optical Society of America.
