Abstract

We report a broadband polarization-independent wavelength conversion by reducing the dispersion discrepancy between the fundamental transverse electric (TE) and transverse magnetic (TM) modes in a silicon nanowire waveguide, through optimizing of the waveguide geometry. The size of the waveguide is optimized to 780nm×795nm (height×width) to ensure that the TE and TM zero-dispersion wavelengths locate at 1550nm, and the group velocity dispersion difference between the TE and TM modes is less than 33ps/(nm·km) in the wavelength range of 1300–1800 nm. Based on an angled-polarization pumped four-wave mixing scheme, a 1 dB polarization-independent bandwidth of 400 nm is achieved in a 0.8 cm-long optimized waveguide when the pump is set at 1553 nm. The tolerance to the pump angle detuning is also strengthened in the optimized waveguide.
