A photodiode is a light-sensitive semiconductor diode. It produces current when it absorbs photons. The package of a photodiode allows light (or infrared or ultraviolet radiation, or X-rays) to reach the sensitive part of the device. The package may include lenses or optical filters. Devices designed for use … See more A photodiode is a PIN structure or p–n junction. When a photon of sufficient energy strikes the diode, it creates an electron–hole pair. This mechanism is also known as the inner photoelectric effect. If the absorption … See more Any p–n junction, if illuminated, is potentially a photodiode. Semiconductor devices such as diodes, transistors and ICs contain p–n junctions, and will not function correctly if … See more P–n photodiodes are used in similar applications to other photodetectors, such as photoconductors, charge-coupled devices (CCD), and photomultiplier tubes. They may be used to … See more Avalanche photodiodes are photodiodes with structure optimized for operating with high reverse bias, approaching the reverse breakdown voltage. … See more The material used to make a photodiode is critical to defining its properties, because only photons with sufficient energy to excite See more Critical performance parameters of a photodiode include spectral responsivity, dark current, response time and noise-equivalent power. Spectral responsivity The spectral responsivity is a ratio of the generated photocurrent to … See more A one-dimensional array of hundreds or thousands of photodiodes can be used as a position sensor, for example as part of an angle sensor. A two-dimensional array is used in image sensors and optical mice. In some applications, photodiode arrays allow for high-speed … See more WebLED (Light emitting diode) is a type of P-N junction diode that emits light when configured in forward bias. It converts electrical energy into light energy & the color of the light depends on the energy gap of the semiconductor. LED Bi-color It is a type of LED that has two different colors of LEDs connected in antiparallel inside single package.
