The characterization of a Balanced Modulation and Detection analog optical link is presented.
The link consists of a pair of low-biased DFB lasers modulated in a push-pull manner and a balanced photodetector. The measured link noise shows an enhancement of 15 dB around the laser threshold and large intermodulation distortion is observed due to imperfections in the half-wave rectification process. The link noise and distortion can be suppressed up to 10 and 30 dB, respectively, if the RF signal is externally half-wave rectified prior to the optical modulation.
