Researchers at MIT, Harvard and the Vienna University of Technology have developed a proof-of-concept optical switch that can be controlled by a single photon and is the equivalent of a transistor in ...

Researchers claim to have fabricated the first all-optical transistor on a silicon chip. This device allows the transmission of light emitted by one laser to be governed by the intensity of another.

Transistors, the tiny switches that flip on and off inside computer chips, have long been the domain of electricity. But scientists are beginning to develop chip components that run on light. Last ...

Optical computing - using light rather than electricity to perform calculations - could pay dividends for both conventional computers and quantum computers, largely hypothetical devices that could ...

Researchers from ETH Zurich have recently managed to create an optical transistor from a single molecule in what is yet another important achievement on the road to quantum computing. Quantum ...

A recent study led by researchers in Spain demonstrates that a single nano-diamond can be operated as an ultrafast single-emitter optical switch operating at room temperature. A recent study led by ...

A fundamental road block for all-optical information processing is the difficulty in realizing a silicon optical transistor with the ability to provide optical gain, input output isolation and buffer ...

Optical connections are slowly replacing wires as a means of shuffling bits in between systems—there are already plans afoot to have different components within a single system communicate via an ...

Optoelectronics, the use of electronic devices for the detection and control of light, has become a preferred means for broadband and transoceanic communication networks. Below is a sneak peek at the ...

LED headlights in cars require precise intensity control over lifetime and over temperature. Automotive headlight control levels typically require multiple nested closed control loops to compensate ...

Electrons are pretty good at processing information but not so good at carrying it over long distances. Photons, on the other hand, do a grand job of shuttling data round the planet but are not so ...
