N2 - A new passive TE/TM-mode polarization filter for an InGaAsP/InP material system based on an asymmetric twin waveguide (ATG) and resonant coupling is investigated. Linear taper sections with different taper angles are introduced to couple between the two vertically separated waveguides. At a wavelength of 1.55 μm extinction ratios (ER) of 20 dB for the TE- and more than 10 dB for the TM-mode are reported for devices shorter than 400 μm. Furthermore we show, this concept can be expanded to a polarization splitter.
