optical energy conversion
1Energy harvesting — (also known as Power harvesting or energy scavenging ) is the process by which energy is captured and stored. Frequently this term is applied when speaking about small autonomous devices, like those used in sensor networks. A variety of different …
2Energy — This article is about the scalar physical quantity. For other uses, see Energy (disambiguation). Energetic redirects here. For other uses, see Energetic (disambiguation) …
3Optical heterodyne detection — is an important special case of heterodyne detection. In heterodyne detection, a signal of interest at some frequency is non linearly mixed with a reference local oscillator (LO) that is set at a close by frequency. The desired outcome is the… …
4Optical character recognition — Optical character recognition, usually abbreviated to OCR, is the mechanical or electronic translation of scanned images of handwritten, typewritten or printed text into machine encoded text. It is widely used to convert books and documents into… …
5Optical IP Switching — (OIS), is a novel method of creating transparent optical connections between network nodes using a flow based approach. An IP flow is a collection of IP packets going from the same source to the same destination: the exchange of IP packets is the …
6Optical downconverter — (ODC) is an example of a non linear optical process, in which two beams of light of different frequencies ω1 and ω2 interact, creating microwave with frequency ω3 = ω1 − ω2. It is a generalization of microwave. In the latter, ω1 = ω2, both of… …
7Optical amplifier — An optical amplifier is a device that amplifies an optical signal directly, without the need to first convert it to an electrical signal. An optical amplifier may be thought of as a laser without an optical cavity, or one in which feedback from… …
8Optical modulators using semiconductor nano-structures — Contents 1 Optical modulators using semiconductor nano structures 1.1 Electro optic modulator of nano structures 1.2 Acousto optic modulator of nano structures …
9Optical frequency multiplier — An optical frequency multiplier is a nonlinear optical device, in which photons interacting with a nonlinear material are effectively combined to form new photons with greater energy, and thus higher frequency (and shorter wavelength). Two types… …
