(Nanowerk Spotlight) Lasers power modern life, from fiber optic networks that drive internet communications to precision tools that enable complex surgery. Most commercial lasers emit light at fixed ...

Inside most photonic chips, light races through tiny optical wires. It carries information far faster than electricity can in many conventional systems. But once that light is trapped on the chip, ...

Blue lasers with surface gratings are delivering quantum precision from millimetre footprints. The visible spectrum is an exciting frontier for laser diode technology. Here emerging applications exist ...

Researchers at the Massachusetts Institute of Technology and partner institutions have developed a photonic ...

Quantum dot lasers and semiconductor photonics constitute a transformative field within modern optoelectronics, offering unique advantages for high‐density photonic integration and next‐generation ...

For the first time ever, scientists have used a technique called "quantum squeezing" to improve the gas sensing performance of devices known as optical frequency comb lasers. These ultra-precise ...

For experiments that require ultra-precise measurements and control over atoms -- think two-photon atomic clocks, cold-atom interferometer sensors and quantum gates -- lasers are the technology of ...

Mid-infrared light sources serve as a key to accessing the “invisible world.” A broad range of applications, including gas detection, molecular spectroscopy, medical diagnostics, and free-space ...

For many of us, computers have always been a series of zeros and ones. There was one type of compute - it was bits and bytes and we learned to accept that. It was pure - simple, logical. When quantum ...
