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.

Physicists have experimentally demonstrated the feasibility of designing an optical analog of a transistor based on a single silicon nanoparticle. Because transistors are some of the most fundamental ...

Researchers in Switzerland have made the world's smallest optical transistor ever from a single dye molecule. The device, which works by weakening or amplifying a "source" laser beam depending on the ...

A component that could lead to the first practical all-optical transistor has been created by researchers in Ireland. Optical transistors control one beam of light using another beam and are analogous ...

I want to write about something a little different this time. I removed the mechanical scroll wheel rotary encoder from a discarded optical mouse and used it in a little project. I really liked the ...

Encoders are a vital component in many applications that require motion control and feedback information. Whether a system’s requirement is speed, direction, or distance, an encoder produces control ...
