Hello!
I am a Ph.D. student in particle physics and in our lab we need to calibrate some electronics to measure time with hundreds of picoseconds resolution.
The electronics are meant to be connected to MPPCs (a kind of avalanche photodiode). This is why we use a LED to calibrate them ... anyway, the details of the calibration process may not be relevant here.
What I am asking is: what is the best (but relatively inexpensive) device/circuit to drive a LED with very short rise time?
In an ideal scenario, ~100 ps long LED light pulse is what I am looking for.
If less than some hundreds of euros/dollars we might even consider buying some new device.
I don't know if in any of the following links there is what I am looking for:
The LED itself can be any (non-white) commercial LED.
Thank you
