Experimental demonstration of a high efficiency polarization splitter based on a one-dimensional grating with a Bragg reflector underneath

• A one-dimensional grating serving both as a polarization beam splitter and a vertical coupler for silicon photonic circuits is designed, fabricated, and characterized. Bragg reflectors are employed to improve greatly the coupling efficiency. Over 50% efficiency for both polarizations are achieved experimentally, and the extinction ratio between them is also high (-20 dB).
