Hi, all,
We do a lot of photoreceiver testing, so we\'ve gotten reasonably good at
it, including building several test gizmos--amplifiers, pulsers,
filters, and so forth.
I\'ve just posted this app note
<https://electrooptical.net/News/application-note-photoreceiver-testing/>
which may be of some interest to folks who do time- and frequency-domain
testing of medium-speed optical gizmos.
The neatest hack is using the shot noise of the measured DC photocurrent
as a well-calibrated signal source for transimpedance measurements.
Works amazingly well if your TIA is quiet.
Feedback welcome.
Cheers
Phil Hobbs
