Abstract

We demonstrate mid-IR FSO coherent detection at ∼ 3.4 μ m using a native detector for (i) a single 1-Gbaud data channel with various modulation formats, including OOK, QPSK, 16 QAM, and 64 QAM, and (ii) five multi-carrier 1-Gbaud 16-QAM channels. We show >10-dB improvement in receiver sensitivity compared to direct detection using the same detector.
