Abstract :
In this work, compact and efficient polarization splitters using horizontal slotted waveguides are presented. The device is fabricated using Complementary Metal-Oxide-Semiconductor (CMOS) compatible processes, which allows monolithic integration with active drive electronics and other photonic components. The splitter is built using two parallel horizontal slotted waveguides and achieves a TM-TM transmission coefficient higher than -0.2dB over a bandwidth of 1550-1600nm for a small coupling length of 12μm. The presented device is readily implemented in polarization diversity circuits.
