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...

Description
Summary:An indoor 100 Gb&#x002F;s free space optical communication link using an injection locked &#x223C;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 &#x2013;17.5 dBm to achieve the bit error rate forward error correction (BER FEC) threshold of 3.8&#x00A0;&#x00D7;&#x00A0;10<sup>&#x2013;3</sup>. This displays the potential of tunable injection locked far <italic>L </italic>-band quantum-dash lasers, with less scattering loss compared to <italic>C</italic>-band counterpart, as promising light sources in both indoor and outdoor future high speed free space optical information and communication technology.
