Novel ultra-short and ultra-broadband polarization beam splitter based on a bent directional coupler
A novel ultra-short polarization beam splitter (PBS) based on a bent directional coupler is proposed by utilizing the evanescent coupling between two bent optical waveguides with different core widths. An ultra-short (<10μm-long) PBS is designed based on silicon-on-insulator nanowires as an example. Numerical simulations show that the present PBS has a good fabrication tolerance and a very broad band (~200nm) for an extinction ratio of >10dB.
