As indicated in the image below, the die is a PN junction, and a lead is drawn at both ends of the PN junction, and a plastic, glass, or metal material is used as packaging to make a crystal diode. The positive electrode, also known as anode, is pulled from the P region, while ...
1.3.2, where the optical signal comes from the p-type side of the wafer, and the optical window size can be large, independent of the thickness of the intrinsic layer. Sign in to download full-size image Fig. 1.3.2. Geometry of a typical PIN photodetector, where the optical signal is...
When a forward bias voltage is applied to the schottky diode, a large number of free electrons are generated in the n-type semiconductor and metal. However, the free electrons in n-type semiconductor and metal cannot cross the junction unless the applied voltage is greater than 0....
The following image shows the symbol of the photodiode: The symbol of the photodiodeis similar to that of an LED, but here the arrow points inwards. Photodiode Working A photodiode is subjected to photons in the form of light which affects the generation of electron-hole pairs. If the en...
and n+ layers [4]. Therefore, it is also called a PIN diode. The PIN photodiode symbol is shown below, having an anode that is positive and a cathode that is negative with two arrows pointing toward the diode, which demonstrates the incident light (seeFig. 10.1). FromFigs. 10.2and...
