2010 (English)In: IEEE Journal of Selected Topics in Quantum Electronics, ISSN 1077-260X, E-ISSN 1558-4542, Vol. 16, no 1, 250-256 p.Article in journal (Refereed) Published
A proposal for polarization-independent wavelength conversion is presented based on four-wave mixing in a silicon nanowire waveguide using an angled-polarization pump. The principle of polarization independence is introduced and the theoretical model is established. The optimized incident pump polarization angle is obtained for different waveguide geometries, and a polarization-independent bandwidth of 64 nm is achieved with the efficiency fluctuation of less than 1 dB in a 285 nm x 650 nm silicon waveguide. The polarization-independent bandwidth is limited by the larger one of the TE- and TM-mode phase mismatches, and can be enhanced further by carefully tailoring the dispersion characteristics of the silicon nanowire waveguide.
