WebbAs expected, we have a CW signal centered at 193.1 THz with peak power around 0 dBm. However, the other two OSAs have no signals, and this is also expected. Why is this expected? It is expected because the Isolator does not have a signal at each input port. The laser will send a signal to the first input port of the isolator. WebbThe intrinsic cutoff frequencies of these Schottky junction devices exceed 1 THz, making them well-suited for use in mixers and detectors operating in the frequency bands from 60 GHz into the hundreds of GHz bands.
