Carrollton, Texas – Optek Technology's OPB819 optical switch consists of a 50-mA infrared-emitting diode and an npn silicon phototransistor mounted in a plastic housing on opposite sides of a 1.25- ...

An all-optical fiber-optic switching device that maintains the signal as light from input to output. Traditional switches that connect optical fiber lines are electro-optic. They convert photons from ...

Fujitsu Laboratories has unveiled a new optical switch technology that it claims uses half the power of conventional optical switches. The new optical waveguide switch uses photonics made from silicon ...

A one-way system for light rays could allow optical computer chips to overtake their standard electronic counterparts. The new device should eventually help to improve the speed of data processing and ...

Integrated circuit technologies are enabling intelligent, chip-based, optical packet switch matrices. Rapid real-time re-configurability at the photonic layer using integrated circuit technologies is ...

An Ethernet transceiver from Firecomms of Cork, Ireland, now comes in a housing that allows instant termination of bare plastic optical fibre (POF). The company says the new POF port, OptoLock, on the ...

(Nanowerk Spotlight) Silicon transistors have been made smaller year after year, but they are approaching a point of physical limitation. Their increasingly small dimensions, now reaching well into ...

Alphabet’s CapitalG, Microsoft’s M12, Micron Ventures, and NVIDIA join forces to back optical switch startup tackling communication bottlenecks in data centers, high-performance computing (HPC), and ...

An 'all-optical switch' is a device that uses light to control other optical signals without the need for electrical conversion, saving both time and energy in optical communications. A research team ...

PIN diodes are ideal for transmit-receive (TR) switches because of a favorable blend of cost, size, and switching speed. Although the PIN diode in the transmit (Tx) arm can be connected as either ...
