A D-band vector millimeter wave (mm-wave) signal generation and propagation scheme employing cascaded intensity modulator (IM) and in-phase/quadrature (I/Q) modulator is proposed and implemented. In experiment, both the IM and I/Q modulator are operating on optical-carrier-suppressing (OCS) mode to generate two pairs of dual single-sideband (SSB) signals, and the undesired optical sidebands are not eliminated by an optical filter. For each pair of dual SSB signals, one is unmodulated the other is vector-modulated, they are located on both sides of the center suppressed carrier. After optical fiber transmission, SSB signals will beat with each other at the photoelectric detection end, thus the electrical mm-wave signals are generated. We experimentally demonstrated 2-Gbaud 16QAM, 4-Gbaud QPSK, and 8-Gbaud QPSK Radio-over-Fiber (RoF) transmission at 130-GHz over 22.5 km standard single mode fiber and 1 m wireless link with a Bit-Error-Rate (BER) under ${3}{{.8}} \times {1}{{0}^{{{ - 3}}}}$.

D波段毫米波产生和通过光纤无线电系统传输

提出并实现了采用级联强度调制器 (IM) 和同相/正交 (I/Q) 调制器的 D 波段矢量毫米波 (mm-wave) 信号生成和传播方案。在实验中，IM和I/Q调制器都工作在光载波抑制（OCS）模式下，产生两对双单边带（SSB）信号，不需要的光边带没有被滤光片消除。对于每对双 SSB 信号，一个是未调制的，另一个是矢量调制的，它们位于中心抑制载波的两侧。光纤传输后，单边带信号在光电检测端相互拍打，从而产生毫米波电信号。我们通过实验演示了 2-Gbaud 16QAM、4-Gbaud QPSK、
