With the explosive growth of data traffic, it is highly desired to develop hybrid photonic integrated circuits combining various optical components on a single chip. Silicon is an outstanding material ...

A research group led by 2014 Nobel laureate Hiroshi Amano at Nagoya University's Institute of Materials and Systems for Sustainability (IMaSS) in central Japan, in collaboration with Asahi Kasei ...

Laser technology as we know it was first realized in 1951 when Charles Townes envisaged the concept of microwave amplification by stimulated emission of radiation (MASER) on a park bench in Washington ...

A compact ultraviolet-B (UV-B) semiconductor laser diode emitting at 318 nm under continuous-wave operation at room-temperature. The device demonstrates stable UV-B lasing on a low-cost sapphire ...

A continuous Bose–Einstein condensate (BEC) has been produced by researchers in the Netherlands. Claimed as a first, the achievement has been sought for years and could lead to continuous-wave atom ...

Chinese research team achieved a major breakthrough in continuous-wave vacuum ultraviolet (VUV) light sources, a longstanding bottleneck in the development of the nuclear clock, Science and Technology ...

For as long as small, hidden radio transmitters have existed, people have wanted a technology to detect them. One of the more effective ways to find hidden electronics is the nonlinear junction ...
