Quantum photonics is one of the important research directions in the quantum field, which utilizes the unique properties of light at the quantum level. The core of this field is the deterministic single photon source, which sequentially emits individual photons through spontaneous emission and is the cornerstone of quantum communication, computing, and secure encryption. However, under environment...
At present, the navigation system has become an important equipment on ships, aircraft, missiles, automobiles and other navigational vehicles. Laser Doppler radar has become an important development direction in the field of velocity measurement technology because of its high accuracy, good spatial resolution and fast dynamic response. The application of the three-beam Doppler Lidar in the...
A Boston University research project has successfully developed an innovative single-cell sorting technique that uses stimulated Raman spectroscopy to replace traditional fluorescent labeling and achieve labeling free and non-destructive single-cell measurements. This technology is expected to have a profound impact in the fields of cytology, microbiology and biomedical research, allowing scienti...
Recently, the research team of the High Power Laser Element Technology and Engineering Department of the Shanghai Institute of Optics and Fine Mechanics, Chinese Academy of Sciences, has made new progress in evaluating the laser damage resistance and damage mechanism of 532nm thin film polarizers using different laser damage test protocols. The related achievements were published in Optical Materi...
Topological laser (TL) is an ideal light source for future new optoelectronic integrated chips, designed and manufactured using topological optics principles to obtain robust single-mode lasers. Electrically pumped topology lasers have become a research hotspot due to their small size and ease of integration, but topology lasers based on electrical injection are still in the early stages of resear...
