An optical module is a typically hot-pluggable optical transceiver used in high-bandwidth data communications applications. Optical modules typically have an electrical interface on the side that connects to the inside of the system and an optical interface on the side that connects to the outside world through a fiber optic cable.
Photonic integrated circuits use photons (or particles of light) as opposed to electrons that are used by electronic integrated circuits. The major difference between the two is that a photonic integrated circuit provides functions for information signals imposed on optical wavelengths typically in the visible spectrum or near-infrared (850 ...
The technical details of coherent optical modules were proprietary for many years, but have recently attracted efforts by multi-source agreement (MSA) groups and a standards development organizations such as the Optical Internetworking Forum. Coherent optical modules can either plug into a front panel socket or an on-board socket.
[3] [48] An important example is all-optical switching, whereby the routing of optical signals is directly controlled by other optical signals. [49] Another example is all-optical wavelength conversion. [50] In 2013, a startup company named "Compass-EOS", based in California and in Israel, was the first to present a commercial silicon-to ...
Stewart David Personick (born 1947) is an American researcher in telecommunications and computer networking.He worked at Bell Labs, TRW, and Bellcore (now Telcordia Technologies), researching optical fiber receiver design, propagation in multi-mode optical fibers, time-domain reflectometry, and the end-to-end modeling of fiber-optic communication systems.
Free-space optical communication (FSO) is an optical communication technology that uses light propagating in free space to wirelessly transmit data for telecommunications or computer networking. "Free space" means air, outer space, vacuum, or something similar. This contrasts with using solids such as optical fiber cable.
The embedded optical link provides complete electrical isolation between the air interface and the electronic circuitry, which is located only after the photodetector (PD). Fig. 2 Details of the receiver front-end design. a, Three-dimensional drawing of the DRA.
Optical chip may refer to: An integrated circuit that acts as the electrical-optical interface for fiber-optic communication; A vision chip which combines optical sensors and computation; A chip used in optical computing. A photonic integrated circuit; A chip that uses an optical interconnect
