We present the design, fabrication, and operation of a polarization converter based on angled waveguides in the InP InGaAsP material system. By combining design elements from mode evolution and birefringent devices, the total device length is kept short (less than 50 μ m ) and the insertion efficiency high at 81 % ± 19 % , which corresponds to an insertion loss of 1 dB . Devices operate broadband, i.e., the polarization conversion exceeds 15 dB over a 100 nm wavelength range. A polarization rotator with these specifications is a prime candidate for use in an integrated polarization diversity scheme.
