1.3 μm all-VCSEL low complexity coherent detection scheme for high bit rate and high splitting ratio PONs

Full 1.3 μm VCSEL-based simplified coherent detection receiver is demonstrated at 5 Gbps. Receiver sensitivity of -34 dBm is achieved providing link reach and splitting ratio extension for future passive optical access networks.
