Broadband Polarization Beam Splitter by Using Cascaded Tapered Bent Directional Couplers

We propose and demonstrate a broadband silicon-based polarization beam splitter (PBS) by using cascaded tapered bent directional couplers (DCs). In our device, the TM-polarized light is efficiently cross coupled to the cross port due to the strong coupling in the DCs, while the TE-polarized light go...
