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.
This journal covers research in experiment, theory, and applications of photonic crystals and photonic band gaps. Additionally, the journal focuses on topics concerning the development of faster telecommunications and the transition from computer-electronics to computer-photonics. Coverage also includes the general topic of fabrication of ...
At the same time, photonics and plasmonics can complement each other, since, under the right conditions, optical signals can be converted to SPPs and vice versa. One of the biggest issues in making plasmonic circuits a feasible reality is the short propagation length of surface plasmons.
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 ...
Photonics Focus is the Society's bimonthly membership magazine focused on photonics applications, career development, and the photonics industry. The magazine launched in January 2020 replacing SPIE Professional , which was the Society's quarterly magazine that covered optics industry insights, technology overviews, and career trends.
Unlike electronic integration where silicon is the dominant material, system photonic integrated circuits have been fabricated from a variety of material systems, including electro-optic crystals such as lithium niobate, silica on silicon, silicon on insulator, various polymers, and semiconductor materials which are used to make semiconductor lasers such as GaAs and InP.
This article lists the companies worldwide engaged in the development of quantum computing, quantum communication and quantum sensing.Quantum computing and communication are two sub-fields of quantum information science, which describes and theorizes information science in terms of quantum physics.
