From a functional standpoint, they can be regarded as the semiconductor analog of photomultipliers.The avalanche photodiode (APD) was invented by Japanese engineer Jun-ichi Nishizawa in 1952. A PN junction photodiode is made of two layers namely p-type and n-type semiconductor whereas PIN photodiode is made of three layers namely p-type, n-type and intrinsic semiconductor. 3. Photodiodes: PIN diode • The PIN diode has heavily doped p-type and n-type regions separated by an intrinsic region, which is a major absorption layer • When reverse biased, it acts like a constant capacitance and when forward biased it behaves as a resistor • The forward resistance of the intrinsic region decreases with increasing current.

In PIN photodiode, an addition layer called intrinsic semiconductor is placed between the p-type and n-type semiconductor to increase the minority carrier current. The PIN photodiode is developed to increase the minority carrier current and response speed. The high resistive layer of the intrinsic region provides the large electric field between the P and N-region.
