The construction and working of photodiode is almost similar to the normalp-n junction diode. PIN (p-type, intrinsic and n-type) structure is mostly used for constructing the photodiode instead of p-n (p-type and n-type) junction structure because PIN structure provide fast response tim...
The PIN diode is a one type of photo detector, used to convert optical signal into an electrical signal. The PIN diode comprises of three regions, namely P-region, I-region and N-region. Typically, both the P and N regions are heavily doped due to they are utilized for Ohmic contacts....
In this paper the entropy of a pin photodiode which works as a high speed optical receiver was calculated and its dependence on the external conditions (laser and bias) was provided. The entropy was minimized with respect to the bias voltage, and optimum coupling condition with laser pulse was...
This type of diode is also called the back diode, and it is not extremely implemented. The backward diode is a PN-junction diode that has a similar operation to a tunnel diode. The scenario of quantum tunneling holds important responsibility in the conduction of the current mainly reverse path...
Following are the pin designations of a color sensor. GND - Power supply ground OE - Enable for output frequency (active low) OUT - Output frequency S0, S1 - Output frequency scaling selection inputs S2, S3 - Photodiode type selection inputs ...

The termination of pin 39 allows the use of differential signal which can turn the photodiode on and off rather faster than using 24V at terminal 35. What must be avoided is the application of greater than 5V between pins 39 and 37 or the photodiode will blow. ...
ANODEPIN 1Pin 1 is an anode pin of IR input within the Optocoupler. It will give the logical input signal to the internal IR. CATHODEPIN 2Pin 2 is the cathode pin of the IR within the optocoupler. It will give the IR to make the common ground with the circuit and Power supply. ...

this property is used to detect the light rays. A photodiode is constructed such that light rays should fall on the PN junction which makes the leakage current increase based on the intensity of the light that we have applied. So, in this way, a photodiode can beused to sense the light...
