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.

Analog and digital optoelectronic sensors combine an LED and an optoelectronic integrated circuit in a compact package to enable optical encoders to provide absolute or incremental position detection ...

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 ...

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 ...

Avago Technologies announced the expansion of its series of miniature reflective incremental optical encoders, which are currently the smallest in the industry, with a new high resolution encoder.
