![]() Optomechanics, which involves the study of the interaction between light and mechanical vibrations of mesoscopic or macroscopic objects.Optoacoustics or photoacoustic imaging where laser energy delivered into biological tissues will be absorbed and converted into heat, leading to ultrasonic emission.Photonics also relates to the emerging science of quantum information and quantum optics. In practice, as the field evolves, evidences that "modern optics" and Photonics are often used interchangeably are very diffused and absorbed in the scientific jargon. Following a source on the response of a query from the publisher of Journal of Optics A: Pure and Applied Physics to the editorial board regarding streamlining the name of the journal reported significant differences in the way the terms "optics" and "photonics" describe the subject area, with some description proposing that "photonics embraces optics. The term electro-optics came into earlier use and specifically encompasses nonlinear electrical-optical interactions applied, e.g., as bulk crystal modulators such as the Pockels cell, but also includes advanced imaging sensors.Īn important aspect in the modern definition of Photonics is that there is not necessarily a widespread agreement in the perception of the field boundaries. ![]() The term optoelectronics connotes devices or circuits that comprise both electrical and optical functions, i.e., a thin-film semiconductor device.
