Converts light energy to electrical energy. The silicone photodiode is most commonly used for relatively fast speeds and good sensitivity in the 0.75um to 0.95um wavelength region. Avalanche photodiodes (APD) combine the detection of optical signals with internal amplification of photocurrent. Internal gain is realized through avalanche multiplication of carriers in the junction region. The advantage in using an APD is its higher signal-to-noise ratio, especially at high bit rates.
In a lightwave system, a device that turns pulses of light into bursts of electricity.
(Receiver) Transforms light into electricity. The silicon photo diode is most commonly used for relatively fast speeds & good sensitivity in the 0.75 um to 0.95 um wavelength region. Avalance photodiodes (ADP) combine the detection of optical signals with internal amplification of photo-current. Internal gain is realized through avalance multiplication of carriers in the junction region. The advantage in using an ADP is its higher signal-to-noise ratio, especially at high bit rates. Physical Address: The MAC-layer address of a node, as opposed to the software-defined network-layer address.
fo to dih tehk tEr] A device used to detect and measure the intensity of radiant energy through photoelectric action.
A solid-state electronic device that converts light intensity into electric current.
Used on the receiving end of a fiber optic cable to convert light energy into electrical energy.
(e.g. photodiode) an electronic device converting optical radiation into electrical signal.
a device that can provide an electrical response that is a useful measure of incident electromagnetic radiation
a quantum device which uses the photon energy of the light to excite electrons and generate a current proportional to the energetic photon flux
A device to detect and measure the intensity of light.
Measures thermal radiation by producing an output through release of electrical changes within its body. They are small flakes of crystalline materials such as US or InSb which respond to different portions of the Spectrum, consequently showing great selectivity in the wavelengths at which they operate.
A device for measuring energy in the photographic band.
An opto-electronic transducer, such as a pin photodiode or avalanche photodiode.
Component used to detect or sense light.
An optoelectronic transducer such as a PIN photodiode (illustrated) or avalanche photodiode. In the case of the PIN diode, it is so named because it is constructed from materials layered by their positive, intrinsic, and negative electron regions.
Photosensors or photodetectors are sensors of light or other electromagnetic energy.
