Abstract

The polarisation characteristics of optical rib waveguides fabricated on the basis of semiconductor and polymer materials are analysed. In particular, the influence of the dimensions and refractive indices on the value of birefringence and the field distributions are investigated. Moreover, the ways of minimizing the value of modal birefringence in large optical waveguides are studied.
