Transducers For Photodiodes
-
Photodiodes convert incoming electromagnetic radiation into electrical charge carriers. If photodiodes are short circuited an electrical current (photocurrent) proportional to the incident radiation intensity (number of photons per second) is induced. These photocurrents are generally small and cover the range from femtoampere (fA) to microampere (µA). Signal transducers transform this weak photocurrent to robust standard signals for reliable data transmission and simple data acquisition.

PIN Photodiode
-
PIN photodiode is a kind of photo detector, it can convert optical signals into electrical signals.This technology was invented in the latest of 1950's. There are three regions in this type of diode. There is a p-region an intrinsic region and an n-region. The p-region and n-region are comparatively heavily doped than the p-region and n-region of usual p-n diodes. The width of the intrinsic region should be larger than the space charge width of a normal p-n junction. The PIN photo diode operates with an applied reverse bias voltage and when the reverse bias is applied, the space charge region must cover the intrinsic region completely. Electron hole pairs are generated in the space charge region by photon absorption. The switching speed of frequency response of photo diode is inversely proportional to the life time. The switching speed can be enhanced by a small minority carrier lifetime. For the photo detector applications where the speed of response is important, the depletion region width should be made as large as possible for small minority carrier lifetime as a result the switch speed also increases.
