Researchers at Busan National University, led by Kwangseuk Kyhm, Professor of Ultra Fast Quantum Optoelectronics from the Department of Optics and Mechatronics, are enhancing signal amplification inside cesium bromide lead perovskite nanosheets through patterned waveguides.Perovskite is a highly attractive material in solar cell applications, but its nanostructure is now being explored as a new la...
The gravitational wave background was first detected in 2016. This was announced after the release of the first dataset by the European pulsar timing array. The second set of data has just been released, combined with the timed array of Indian pulsars, and both studies have confirmed the existence of the background. The latest theory seems to suggest that we are seeing a comprehensive signal of th...
The Near Infrared Red Planet Search Alliance, jointly managed by the Department of Astronomy at the University of Geneva and the University of Montreal, has received cutting-edge advances in CSEM laser frequency comb technology.The laser frequency comb is a precise and stable light source designed to help the NIRPS alliance unravel the mysteries of distant planets, including the possibility of sea...
