Phase locking of multiple optical fiber channels for a slow-light-enabled laser
... The operation of the snapback circuit is as follows: The half-wave voltage (Vπ ) of our EOM is nominally 4 V, and the loop filter uses ±15 V supply voltages. When the loop filter’s output VEOM exceeds 3Vπ (nominally 12 V), an analog switch engages and strongly drives VEOM toward negative voltages. Onc ...

... Do you have a square waveform generator, but not a real pulse generator for testing the integrator? Here is a simple (crude) way to get the pulse you need -- about 1 millisecond long, 1-5 volts high, 50 pulses each second. It generates a more-or-less square pulse on every rising edge of the input sq ...
