Pin diode laser detector.

The following graph shows the detector response curve for different materials. Silicon is commonly used as an inexpensive detector material in the vis range. Silicon pin photodiodes are reverse biased pin diodes which detect light and generate current as a result. Pin photodiode has an intrinsic very lightly doped semiconductor region sandwiched between a p doped and an n doped region as shown below.

The pin photodiode structure has an intrinsic layer within the depletion region which allows high quantum efficiency and fast response for detection of photons. The diode in which the intrinsic layer of high resistivity is sandwiched between the p and n region of semiconductor material such type of diode is known as the pin diode. Osi laser diode inc. Silicon pin photodiodes are available with a wide variety of active areas to accommodate many varied applications.

Silicon pin photodiodes are available with a wide variety of active areas to accommodate many varied applications. A pin diode is a diode with a wide undoped intrinsic semiconductor region between a p type semiconductor and an n type semiconductor region. The wide intrinsic region is in contrast to an ordinary p n diode the wide intrinsic region makes the pin diode an inferior rectifier one typical. The pin photodiode structure allows high quantum efficiency and fast response for detection of photons in the 400nm to 1100nm range.

1310 nm and 1550 nm. It covers the widest spectral range from the vis to the nir. The electric field induces because of the movement of the holes and the electrons. The high resistive layer of the intrinsic region provides the large electric field between the p and n region.

A pin diode comprises a near intrinsic semiconductor region usually the space charge region sandwiched between a p type diode and an n type substrate. A further use of the pin diode is as a photo detector photodetector or photo diode where its structure is particularly suited to absorbing light. Silicon pin photodiodes are reverse biased pin diodes which detect light and generate current as a result. The pin diode receives its name from the fact that is has three main layers.

For higher demands ingaas is used. However the term is also used for components with inverse conductivity provided that no other non linear effects are utilized in the component. The p type and n type regions are typically heavily doped because they are used for ohmic contacts. The most common semiconductor photodetector is the pin photodiode as shown below.

The advantage of a pin diode is that the depletion region exists almost completely within the intrinsic region which has a constant width or almost constant regardless of disturbances applied to the diode. Rather than just having a p type and an n type layer the pin diode has three layers.
