- We developed an analog optical transmitter module with rf gain for 60 GHz radio-over-fiber (RoF) application narrow band. It consists of an electroabsorption modulator (EAM), a filter, and amplifier. The frequency response increased about 20 dB from the noise level around 60 GHz with the EAM bias voltage of -1.6 V. The 3 dB bandwidth was about 2.2 GHz. The signal-to-noise ratio of the RoF link with transmitter module was measured and the noise figure was obtained, which were compared with those of narrow band EAM module with an additional amplifier. A 16 quadrature-amplitude-modulation data signal could be transmitted with the signal-to-noise ratio of 15.9 dB. The noise figure of the RoF link with the transmitter module was calculated 19.2 dB, which is about 7.5 dB larger than that of the EAM module with rf amplifier at the bias voltage -2.0 V. © 2007 Society of Photo-Optical Instrumentation Engineers.
