Lasers with ultra-low threshold and compact size are highly desirable components in photonic integrated circuits, aiming at the application of optical communications, chip-scale solid-state LIDAR and quantum information. ...
Vortices of light, null regions of intensity surrounded by spiral phases, make up the skeleton of a wavefield and influence the properties of light. Since the discovery of the tight connection of optical vortices and orbital ...
Researchers have developed a quantum key distribution (QKD) system based on integrated photonics that can transmit secure keys at unprecedented speeds. The proof-of-principle experiments represent an important step toward ...
Prof. Peng Chenhui's team from the School of Physics, University of Science and Technology of China (USTC), realized the collective transfer and reconfigurable self-assembly of colloidal particles by combining the light-driven ...
Scientists working on laser application at the RIKEN Center for Advanced Photonics (RAP) have employed a new technique using GHz bursts of femtosecond laser pulses grouped in MHz envelopes—termed BiBurst mode—to greatly increase ...
In his famous letter to the Royal Society dated Oct. 9, 1676, Antonie van Leeuwenhoek described a single-celled eukaryote (Vorticella) and its fascinating ultrafast cell contraction. This kind of ultrafast cell contraction ...
Scientists working on laser application at the RIKEN Center for Advanced Photonics (RAP) have developed a new technique using GHz bursts of femtosecond laser pulses grouped in MHz envelopes, termed BiBurst mode, for high-efficiency ...
Researchers have developed a new way to use femtosecond laser pulses to fabricate the high-precision ultrathin mirrors required for high-performance X-ray telescopes. The technique could help improve the space-based X-ray ...
Many things are already possible when it comes to mimicking organic cells. For example, Jan van Hest's group has developed a synthetic cell platform in which all kinds of cell aspects can be mimicked in order to better understand ...
Whereas the shortest way between two points is a straight connection, it might not be the most efficient path to follow. Complex currents often affect the motion of microswimmers and make it difficult for them to reach their ...
