Transistor lasers represent a unique integration of semiconductor light sources with transistor functionalities, enabling both high-speed optical emission and electronic amplification in a single ...

Over the past decades, engineers have introduced numerous technologies that rely on light and its underlying characteristics. These include photonic and quantum systems that could advance imaging, ...

image: Photons do not interact with each other well, which creates a big problem for microelectronics engineers. A group of researchers from ITMO University, together with colleagues, have come up ...

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 ...

(Nanowerk News) An international research team led by Skoltech and IBM has created an extremely energy-efficient optical switch that could replace electronic transistors in a new generation of ...

Physicists in the US and Denmark have unveiled plans for an all-optical transistor-like device that can be turned on by a single photon. The device -- which has not yet been built -- consists of a ...

(Nanowerk Spotlight) On December 26, 1947, the two physicists Walter Brattain and John Bardeen, officially demonstrated the first point-contact transistor at Bell Labs. Later, in January 1948, William ...

Transistors are tiny electronic components that act as switches and amplifiers, and they dwell at the heart of modern technology. In simple terms, a transistor can turn a flow of electricity on or off ...
