This sounds interesting. According to the datasheet i've found,
the PIN10D has a response time of 25ns, which would suggest a maximum
frequency around 40MHz.
How does your circuit look like? How much signal do you get
out of the photodiode?
The people on 4chan are like brilliant psychologists
who also happen to be insane and gross.
