What is the use of PIN photodiode?

They are used in Photodetectors and photovoltaic cell and the PIN photodiodes are used for fibre optic network cards and also switches. These diodes are effectively used for RF protection circuits and it can also be utilized as an RF switch. The PIN photodiode is also used to detect X-rays and gamma rays photons.

What does I in PIN photodiode stands for?

A p–i–n photodiode, also called PIN photodiode, is a photodiode with an intrinsic (i) (i.e., undoped) region in between the n- and p-doped regions. Most of the photons are absorbed in the intrinsic region, and carriers generated therein can efficiently contribute to the photocurrent.

What are the advantages of PIN photodiode over PN photodiode?

PIN photodiode basics The PIN photodiode provides additional sensitivity and performance over that of the basic PN junction photodiode. One of the key requirements for any photodetector is a sufficiently large area in which the light photons can be collected and converted.

What are the drawbacks of PIN photodiode?

Advantages and Disadvantages of PIN Photodiode These diodes have a broad spectral response and they can process even very weak signals. The disadvantage of PIN diode is that it requires large reverse bias for its operation which sometimes reduces the signal to noise ratio.

What are the physical principles of PIN photodiode?

What can a PIN photo diode be used for?

The PIN photo-diode does not have any gain, and for some applications this may be a disadvantage. Despite this it is still the most widely used form of diode, finding applications in audio CD players, and DVD drives, etc. In addition to this they are used in optical communication systems. PIN photodiode are also used as nuclear radiation detectors.

What is the cutoff frequency for a Si PIN photodiode?

†Cutoff frequency: 10 MHz or more IR-enhanced Si PIN photodiode These photodiodes have fine structures fabricated on the back side of the photosensitive area and feature improved sensitivity in the near infrared region above 900 nm.

What can a p-i-n photodiode be used for?

They are often made in fiber-coupled form and can be applied e.g. in receivers for optical fiber communications; the achieved bit rates can be as high as 160 Gbit/s. Some p–i–n diodes are based on silicon. They are sensitive throughout the visible spectral region and in the near infrared up to ≈ 1 μm.
