A type of diode used as a light detector in optical transmission systems. A PIN comprises three layers of semiconducting material in the forward current-carrying direction. The first layer is chemically doped, i.e., infused with impurities, to create a positive (p) electromagnetic region.The second layer is either undoped or lightly doped to retain its intrinsic (i) properties and, therefore, is neither strongly positive nor strongly negative. The third layer is doped to create a negative (n) electromagnetic region. So, the diode structure is Positive, Intrinsic, and Negative, or PIN. A PIN generates a single electron from each photon received and, therefore, does not provide a significant gain, or increase in signal strength. However, PINs are fairly rugged and inexpensive. PINs generally are matched with light-emitting diode (LED) and vertical cavity surface-emitting laser (VCSEL) light sources and multimode (MMF) glass optical fiber (GOF) or plastic optical fiber (POF) in relatively low speed, short haul fiber optic transmission systems (FOTS). See also diode, dopant, FOTS, GOF, laser diode, LED, light detector, MMF, POF, and VCSEL.

Origin of pin

  • Middle English from Old English pinn perhaps from Latin pinna feather pet- in Indo-European roots
    From American Heritage Dictionary of the English Language, 5th Edition
  • From Middle English pinne, from Old English pinn (“pin, peg, bolt"), from Proto-Germanic *pinnaz, *pinnō, *pint- (“protruding point, peak, peg, pin, nail"), from Proto-Indo-European *bend- (“protruding object, pointed peg, nail, edge"). Cognate with Dutch pin (“peg, pin"), Low German pin, pinne (“pin, point, nail, peg"), German Pinn, Pinne (“pin, tack, peg"), Bavarian Pfonzer, Pfunzer (“sharpened point"), Danish pind (“pin, pointed stick"), Norwegian pinn (“knitting-needle"), Swedish pinne (“peg, rod, stick"), Icelandic pinni (“pin"). More at pintle.
    From Wiktionary
  • No relation to classical Latin pinna (“fin, flipper, wing-like appendage, wing, feather"), which was extended to mean "ridge, peak, point" (compare pinnacle), and often confused with Latin penna (“wing, feather"). More at feather.
