Colorless Coherent Receiver Using 3x3 Coupler Hybrids and Single-Ended Detection
16 January 2012
We demonstrate a single-ended colorless coherent receiver using symmetric 3x3 coupler hybrids. This allows for colorless reception of fifty-five 112-Gb/s PDM-QPSK channels with 1.0-dB penalty and the receiver works well after transmission over 2560-km TrueWaveREACH-fiber. OCIS codes: (060.2330) Fiber optics communications; (060.1660) Coherent communications; (040.1880) Detection
