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 ...

A high-performance ‘photonic transistor’ that switches light signals instead of electronic signals could revolutionize optical signal processing. Electronic transistors, which act as miniature ...

Optical circuits use light instead of electricity, making them faster and more energy-efficient than electrical systems. Scientists have developed a first building block for photonic 'transistors' ...

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 ...

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 ...

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 ...
