Abstract: We propose and experimentally demonstrate an ultra-compact, low-loss polarization-independent directional coupler on the silicon-on-insulator (SOI) platform. By exploiting subwavelength gratings in the directional coupler, the coupling strength could be made equal for both transverse-electric and… read more here.

Abstract: Ultra-compact polarization-independent directional couplers are proposed and demonstrated on the silicon-on-insulator (SOI) platform. By using the subwavelength structure in the coupling region, the coupling strength is greatly enhanced only for TE polarization, so that the… read more here.
