Datasheet, Photo |
● Photodiodes are less resistant. They are quick and have a high speed to operate.
● These photodiodes have a long lifespan and are considered the fastest photodetector.
● The spectral response of the photodiode is good and does not need high voltage to operate.
● The photodiode has a high quantum efficiency with less noise.
P-N JUNCTION
This is the most basic photodiode. The physics of how the P-N junction photodiode operates was reviewed earlier. The PIN and APD photodiode are variations from the P-N junction.
The depletion region contains few free charge carriers, and the width of the depletion region can be manipulated by adding voltage bias.
Current passing through the photodiode can only flow in one direction based on the P and N doped materials. If reverse biased, current will not flow through a photodiode without incident light creating photocurrent.
PIN Photodiode
The PIN photodiode is similar to the P-N Junction with one major difference. Instead of placing the P and N layers together to create a depletion region, an intrinsic layer is placed between the two doped layers. This layer is shown in Figure 2. This intrinsic layer is highly resistive and increases the electric field strength in the photodiode. There are many benefits to the added intrinsic layer because the depletion region is greatly increased.
Avalanche Photodiode
Avalanche photodiodes (APD) use impact ionization (avalanche effect) to create an internal gain in the material. APDs require high reverse bias operation (near reverse breakdown voltage). Each photo-generated carrier creates more pairs and so is multiplied by avalanche breakdown. This creates internal gain within the photodiode, which in turn increases the effective responsivity (larger current generated per photon).
The two-layer PN-junction semiconductor diode has many uses in the field of electrical and electronic engineering. They can be used in rectifiers, voltage regulation and wave-shaping circuits. But they are also extremely useful as optoelectronic devices in which one type of diode allows light to control its current. While another type of diode emits light when passing a current. These two devices are the Photodiode and the Light Emitting Diode (LED) respectively.
Unlike the light-emitting diode which produces or emits light, the photodiode is a photo detector which receives light and converts it into an electrical signal. A junction photodiode operates based on the photoelectric effect.
In total darkness, the diode junction has a relatively high internal resistance and therefore blocks current. However, when sufficient light energy strikes its semiconductor junction, the dynamic resistance of its junction decreases allowing more current to flow. Thus, photodiodes have a photoconductive gain.
● Photodiodes are used in simple day-to-day applications. The reason for their prominent use is their linear response of photodiode to light illumination.
● Photodiodes with the help of optocouplers provide electric isolation. When two isolated circuits are illuminated by light, optocouplers are used to couple the circuit optically. Optocouplers are faster compared to conventional devices.
● Photodiodes are used in safety electronics such as fire and smoke detectors.
● Photodiodes are used in numerous medical applications. They are used in instruments that analyze samples, detectors for computed tomography and also used in blood gas monitors.
● Photodiodes are used in solar cell panels.
● Photodiodes are used in logic circuits.
● Photodiodes are used in the detection circuits.
● Photodiodes are used in character recognition circuits.
● Photodiodes are used for the exact measurement of the intensity of light in science and industry.
● Photodiodes are faster and more complex than normal PN junction diodes and hence are frequently used for lighting regulation and optical communication.
