Abstract
Polarization beam splitters based on three-core photonic crystal fibers are presented. The two different polarizations of the input field are separated to the horizontal and vertical output ports. The splitter design has been done through modal and beam propagation analysis with high performance codes based on the finite element method. Device length of few mm and extinction ratios between -14 dB and -23 dB have been obtained for bandwidths up to 90 nm.
