Abstract :
The waveguide-type optical polarization splitter, which utilizes birefringence of a Langmuir-Blodgett cladding layer, is studied theoretically and experimentally. By means of the beam propagation method based on Galerkin´s principle, characteristics of the polarization splitter are analyzed. Results of the numerical calculation predict excellent polarization splitting properties with a crosstalk of -30 dB and an insertion loss of less than 0.1 dB for both TE and TM polarization. Successful operation of the polarization splitter was demonstrated in an experimental device
