An optical transistor, also known as an optical switch or a light valve, is a device that switches or amplifies optical signals.Light occurring on an optical transistor's input changes the intensity of light emitted from the transistor's output while output power is supplied by an additional optical source.
When the laser and laser diode were invented in the 1960s, the term "photonics" fell into more common usage to describe the application of light to replace applications previously achieved through the use of electronics. By the 1980s, photonics gained traction through its role in fibre optic communication.
A further array-based switch engine uses an array of individual reflective MEMS mirrors to perform the necessary beam steering (Figure 5 [5] (to be uploaded). These arrays are typically a derivative of the Texas Instruments DLP range of spatial light modulators. In this case, the angle of the MEMs mirrors is changed to deflect the beam.
ACS Photonics is a monthly, peer-reviewed, scientific journal, first published in January 2014 by the American Chemical Society. The current editor in chief is Romain Quidant ( ETH Zurich ). The interdisciplinary journal publishes original research articles, letters, comments, reviews and perspectives.
