The project describes the operation of a cheap keychain lasers that are being sold in low price. In theory, most common laser heads contains two semiconductors inside which includes a laser diode (LD) ...

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 ...

Researchers transformed red marker ink into graphene-based circuits using a laser, enabling low-cost, flexible electronics on everyday surfaces like paper or cups. (Nanowerk News) It is the first case ...

Well, here’s a cooooool finding. Take any piece of electronic equipment you can think of and its circuits are powered by, yes, electrons. But a new experiment takes us one step closer to “atomtronic ...

Boise State University researchers have unveiled a cutting-edge approach to manufacturing flexible hybrid circuits—reducing costs, waste, and environmental impact. Their work leverages the properties ...

Most of us have Ethernet in our homes today. The real backbones of the Internet though, use no wires at all. Optical fibers carry pulses of light across the land, under the sea, and if you’re lucky, ...

Photonic chips with quantum lasers are finally being built without redesigning the whole system These lasers work directly on silicon and still survive high heat for over six years University of ...

The tiny copper wires that connect different areas of an integrated circuit may soon limit microchip-processing speeds. So European researchers have developed technologies to produce and combine ...

Most everyone is familiar with lasers in someway or another, be it Darth Vader’s light sword or lasers used by surgeons to perform intricate operations on, say, the eye retina. And, no doubt, ...
