Editing Photonics (section)

===Emerging fields===
Photonics also relates to the emerging science of [[quantum information]] and quantum optics. Other emerging fields include:

* [[Photoacoustic imaging|Optoacoustics or photoacoustic imaging]] where [[laser]] energy delivered into biological tissues will be absorbed and converted into heat, leading to [[ultrasonic]] emission. 
* [[Optomechanics (science)|Optomechanics]], which involves the study of the interaction between light and mechanical vibrations of mesoscopic or macroscopic objects; 
* [[Optomics]], in which devices integrate both photonic and atomic devices for applications such as precision timekeeping, navigation, and metrology; 
* [[Plasmonics]], which studies the interaction between light and [[plasmon]]s in dielectric and metallic structures. Plasmons are the quantizations of [[plasma oscillation]]s; when coupled to an electromagnetic wave, they manifest as [[surface plasmon polariton]]s or [[localized surface plasmon]]s. 
* [[Polaritonics]], which differs from photonics in that the fundamental information carrier is a [[polariton]]. Polaritons are a mixture of photons and [[phonons]], and operate in the range of frequencies from 300 [[gigahertz]] to approximately 10 [[Terahertz (unit)|terahertz]].
* [[Programmable photonics]], which studies the development of photonic circuits that can be reprogrammed to implement different functions in the same fashion as an [[FPGA|electronic FPGA]]
