Little Laser Trip Wire circuit presented here can detect movement of people or objects while passing through the laser beam and trigger security alarms as alert signals to those concerned. What is ...

Expensive semiconductor laser diodes have no tolerance for fast voltage or current transients. To minimize the risk of damage, a standard JFET-clamp circuit shorts the laser when there is no supply ...

The first circuit of ultracold atoms has been unveiled by physicists in the US. The team has already shown how the atomic current in the circuit can be controlled precisely and believes that similar ...

For small volume production, the Fusion3D 1100 system creates three dimensional circuits and laser-structuring of molded interconnect devices. Reportedly, the system is quite compact, making it easy ...

Quantum communication has long promised unbreakable encryption, but the hardware has struggled to escape the lab. A new generation of laser-written glass chips is changing that equation, carving three ...

The National Technical University of Athens in Greece has developed a method for potentially ushering in an age of cheaper electronics. The researchers successfully created polymer circuits using ...

Taken from the 2022 Physics World Optics and Photonics Briefing, where it appeared under the headline "Inscribing the way to a brighter future". VitreaLab, a photonics start-up based in Vienna, was ...

Manufacturers of electronic components with printed-circuit boards (PCBs) have a new method for mounting PCBs to their respective thermoplastic housings or substrates: laser staking. The technology ...
