Photonics is a branch of optics that involves the application of generation, detection, and manipulation of light in the form of photons through emission, transmission, modulation, signal processing, switching, amplification, and sensing.
Optical computing or photonic computing uses light waves produced by lasers or incoherent sources for data processing, data storage or data communication for computing.For decades, photons have shown promise to enable a higher bandwidth than the electrons used in conventional computers (see optical fibers).
The platforms considered most versatile are indium phosphide (InP) and silicon photonics (SiPh): Indium phosphide (InP) PICs have active laser generation, amplification, control, and detection. This makes them an ideal component for communication and sensing applications. Silicon nitride (SiN) PICs have a vast spectral range and ultra low-loss ...
Optical communication, also known as optical telecommunication, is communication at a distance using light to carry information. It can be performed visually or by using electronic devices . The earliest basic forms of optical communication date back several millennia, while the earliest electrical device created to do so was the photophone ...
The majority of silicon photonic communications have so far been limited to telecom [31] and datacom applications, [32] [33] where the reach is of several kilometers or several meters respectively. Silicon photonics, however, is expected to play a significant role in computercom as well, where optical links have a reach in the centimeter to ...
Laser communication in space is the use of free-space optical communication in outer space. ... Mynaric, SA Photonics (a CACI subsidiary), Skyloom, Tesat-Spacecom [58]
Long-range optical wireless communication or 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 over long distances. "Free space" means air, outer space, vacuum, or something similar.
Integrated quantum photonics, uses photonic integrated circuits to control photonic quantum states for applications in quantum technologies. [ 1 ] [ 2 ] As such, integrated quantum photonics provides a promising approach to the miniaturisation and scaling up of optical quantum circuits . [ 3 ]
