Abstract
The wideband microwave performance of a laser link was improved using a lossless microwave impedance-matching network. Matching has been achieved from 3 to 9.5 GHz, which is more than one octave with a 5 dB associated improvement in both throughput loss and noise figure for the optical link. The improved noise figure makes it possible to use the laser link with lower-gain amplifiers in front of the laser, and the improved throughput loss reduces the gain needed after the link. It is concluded that impedance matching not only improves the performance but also reduces power consumption in the whole system.
