1Optical performance monitoring — (OPM) is used for managing high capacity dense wavelength division multiplexing (DWDM) optical transmission and switching systems in Next Generation Networks (NGN). OPM involves assessing the quality of data channel by measuring its optical… …
2Optical isolator — This article is about the optical component. For the optoelectronic component, see Opto isolator. An optical isolator, or optical diode, is an optical component which allows the transmission of light in only one direction. It is typically used to …
3Optical coating — Optically coated mirrors and lenses. An optical coating is one or more thin layers of material deposited on an optical component such as a lens or mirror, which alters the way in which the optic reflects and transmits light. One type of optical… …
4Optical hybrid — A 90° optical hybrid is a six port device that is used for coherent signal demodulation for either homodyne or heterodyne detection. It would mix the incoming signal with the four quadratural states associated with the reference signal in the… …
5Optical switch — This article is about the optical component. For the optoelectronic component, see Slotted optical switch. In telecommunication, an optical switch is a switch that enables signals in optical fibers or integrated optical circuits (IOCs) to be… …
6Optical disc recording technologies — Optical discs Optical disc Optical disc drive Optical disc authoring Authoring software Recording technologies Recording modes Packet writing Optical media types …
7Optical power meter — in use An optical power meter (OPM) is a device used to measure the power in an optical signal. The term usually refers to a device for testing average power in fiber optic systems. Other general purpose light power measuring devices are usually… …
8Optical phase space — Optical phase diagram of a coherent state s distribution across phase space. In quantum optics, an optical phase space is a phase space in which all quantum states of an optical system are described. Each point in the optical phase space… …
9Optical rotation — (optical activity) is the turning of the plane of linearly polarized light about the direction of motion as the light travels through certain materials. It occurs in solutions of chiral molecules such as sucrose (sugar), solids with rotated… …
10Optical axis grating — Optical axis gratings (OAGs) are gratings of optical axis of a birefringent material. In OAGs, the birefringence of the material is constant, while the direction of optical axis is periodically modulated in a fixed direction. In this way they are …
