There is an increasing interest in using an integrated optical waveguide as a displacement or pressure sensor. This paper provides a theoretical analysis of 3-D channel waveguides subjected to deformation. The analysis is rather general and can be extended to many practical channel waveguides. The motivation for this paper is to provide the designers of integrated optical sensors simple formulas to evaluate designs and material systems. Our analysis begins with a straight channel guide having an isotropic refractive index. In Section I, we consider the wave solutions to this channel waveguide using the Marcatili method. We give all the pertinent equations for performing first order calculations.
