Colorless devices and reception techniques for polarization multiplexed communications

Future optical networks call for flexible, high performance and low cost coherent optical receivers. We present here several advances towards such receivers, including integrated optical couplers with ultra-broad bandwidth, as well as novel reception techniques and architectures that will enable high performance coherent reception without filtering and polarization splitting elements.Peer reviewed: YesNRC publication: Ye

Ultra-compact polarization mode converter implemented in a dual-trench silicon-on-insulator waveguide

We demonstrate an ultracompact polarization mode converter based on a silicon-on-insulator waveguide with two longitudinal subwavelength trenches. An extinction ratio of 16 dB at 1.5 \u3bcm is achieved for a device length of 10 \u3bcm. \ua9 2012 OSA.Peer reviewed: YesNRC publication: Ye
