We demonstrate an indoor 5 m free-space optical wireless coherent communication in mid L-band（1606.7 nm）by employing a tunable self-seeded InAs/InGaAlAs/InP quantum-dash（Qdash） laser as a subcarrier generator for 128 Gb/s dual-polarization quadrature phase shift keying（DP-QPSK） modulation signal. The bare Qdash laser diode displays ⁶ nm self-locked Fabry–Perot mode tunability with ³0 dB side mode suppression ratio（SMSR） and ¹0 dBm mode power across the tuning ran...
