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 ...

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 ...

The device, developed by researchers from the Faculty of Physics and the Centre for Quantum Optical Technologies, uses ...

Networking specialist ADVA has joined an initiative that aims to speed up data center interconnect (DCI) technology by embedding lasers into silicon chips. The four-year collaborative project, called ...

Hybrid device: the photonic integrated chip developed in this study. (Courtesy: G Likhachev, EPFL) A new type of ultrafast tuneable laser based on low-loss lithium niobate integrated photonics could ...

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 ...

Here at Hackaday we really like to feature projects that push the limits of what’s possible, or ones that feature some new and exciting technology that nobody has ever seen before. So what’s so ...
