Biasing the photodetector

  1. Aug 8, 2014 #1
    I just want to ask why do we bias the photodetector before starting any setup?
    Thank you

    Can you be a little more specific? What kind of photodetector? What is it biased to?

    So I am working in fiber optics and I will convert light signals to electric signals such that the PNA detects them before the PNA there is a photodetector just want to know why should I bias it before time

    I'm not very familiar with fiber optics. What kind of photodetector are you using?

    Try starting with the WIKIPEDIA page for an inroduction.

    Be sure to study it carefully, visit the "see also" entries, check out each "reference" that covers your specific interests, and don't ignore "external links". Here is just one of those:
