1+ day, 23+ hour ago   (186+ words) How do you add an optical isolator to a silicon photonics chip without exposing the entire chip to high temperatures? A laser-based process could solve it. Laser Method Puts Optical Isolators Directly On Silicon Chips The researchers addressed this by…...

1+ day, 12+ 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…...

2+ day, 20+ hour ago   (148+ words) Numerous emerging applications require nanoscale additive manufacturing, in particular, 3D printing, to make increasing strides in manufacturing throughput and resolution. Ultrafast lasers are a uniquely suited tool for spatially and temporally sculpting light fields to enable future advanced 3D nanoprinting methods. Receive…...

1+ week, 12+ hour 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, 1+ day ago   (145+ words) The Illinois researchers’ innovative approach is a practical route forward for high-performance, fully integrated QPCSELs that are versatile and geometry independent. “We’ve demonstrated that we can have a non-periodic pattern and more flexibility to tune it,” Raftery said. “It’s a…...

1+ week, 1+ day ago   (87+ words) Femtosecond lasers, the ultrashort pulsed light sources prized for their ability to carve matter with almost surgical precision, have long promised a route to fabricating display technologies at scales far smaller than conventional lithography can comfortably reach. Now, a team…...

2+ week, 2+ hour ago   (76+ words) A $30 Arduino Machine That Grows Silver Nanostructures Could Put Nanofabrication on Every Lab Bench For decades, sculpting matter at the nanoscale with precise electrical control has meant equipment that costs as much as a car. A team of researchers in…...

2+ week, 23+ hour ago   (93+ words) A burst of femtosecond laser pulses has been used to selectively thin gold plating on electronic bonding pads, addressing a long-standing conflict in advanced packaging. Gold protects contacts and supports reliable wire bonding, but when too much dissolves into molten…...
