Paper Abstract

A new type of waveguide optical polarization splitter is proposed and investigated theoretically. The waveguide optical polarization splitter consists of an Y branch waveguide in which a dielectric periodic multiplayer is loaded on a core of one branch as outer cladding layer. The dielectric periodic multilayer has large birefringence. The branch with the dielectric periodic multiplayer is designed so as the effective refractive index becomes higher than that of another branch for the y-polarization and that becomes lower for the x-polarization. Therefore, the x- and y-polarized waves propagate for different branches each other. The optical losses for the x- and y-polarization have been calculated by using a beam propagating method. The theoretical insertion loss of the typically designed waveguide optical polarization splitter is 0.3 dB. It has also been confirmed that the crosstalk is <-16 dB.
