2+ day, 18+ hour ago   (236+ words) A new optical chip technology from Kyocera and Tohoku University could help solve a growing problem in high-speed data centers by cutting back-reflected light by about 95 percent. That matters because optical isolators prevent light from traveling back toward the laser…...

1+ week, 1+ day ago   (360+ words) By embedding tiny dielectric structures inside the semiconductor, researchers created a laser that can control light in a new way. A laser does not always need a perfectly repeating pattern to produce a clean beam. The device produced single-mode lasing…...

1+ week, 2+ day ago   (365+ words) Researchers have developed a tiny semiconductor device that can change the frequency, or color, of light far more efficiently than conventional designs, potentially shrinking components used in telecommunications and quantum technologies. The device combines specially engineered semiconductor layers with a…...

1+ week, 3+ day ago   (457+ words) QuProtect has secured tactical networks during a live Army exercise. The US Army has tested a quantum-resistant cybersecurity platform under live battlefield conditions, demonstrating its ability to protect tactical communications from emerging quantum threats. QuSecure’s QuProtect R3 was deployed during Project…...

1+ week, 3+ day ago   (397+ words) Inverted perovskite solar cells can reach an energy conversion efficiency of 24.6 percent when treated with a new chemical process. The performance marks a clear step up from standard versions of the device. The gains rely on a two-step method using…...

2+ week, 2+ day ago   (410+ words) Rigaku and Tohoku University have launched a three-year research institute focused on extending X-ray metrology. Rigaku and Tohoku University have opened a research institute aimed at expanding what X-ray metrology can measure inside advanced semiconductor structures. The Rigaku-Tohoku University Co-Creation…...
