4 m/100 Gb/s Optical Wireless Communication Based on Far L–Band Injection Locked Quantum-Dash Laser

An indoor 100 Gb/s free space optical communication link using an injection locked ~1621 nm quantum-dash laser has been experimentally demonstrated. The results are achieved using dual-polarization quadrature phase shift keying (DP-QPSK) and coherent detection over a 4 m indoor free space link. The...

Summary:An indoor 100 Gb/s free space optical communication link using an injection locked ~1621 nm quantum-dash laser has been experimentally demonstrated. The results are achieved using dual-polarization quadrature phase shift keying (DP-QPSK) and coherent detection over a 4 m indoor free space link. The system exhibited a receiver sensitivity of -17.5 dBm to achieve the bit error rate forward error correction (BER FEC) threshold of 3.8 × 10 -3 . This displays the potential of tunable injection locked far L -band quantum-dash lasers, with less scattering loss compared to C-band counterpart, as promising light sources in both indoor and outdoor future high speed free space optical information and communication technology.
