A group of researchers from the Max Planck Institute of Optoelectronics has made a significant breakthrough in using laser cooling to travel sound waves. This development brings us one step closer to the quantum ground state of sound in waveguides, which is of great significance for quantum communication systems and future quantum technology.By using laser cooling, scientists can significantly red...

Scientists from the Federal Institute of Technology in Lausanne (EPFL) have successfully miniaturized a powerful erbium-based erbium laser on silicon nitride photonic chips. Due to the large volume and difficulty in shrinking of typical erbium-based fiber lasers, this breakthrough is expected to make significant progress in optical communication and sensing technology.Since the 1960s, lasers have ...

Recently, Li Hao and You Lixing's team from the Chinese Academy of Sciences Shanghai Institute of Microsystems and Information Technology developed an ultrahigh speed, photon number resolvable optical quantum detector with a maximum count rate of 5GHz and a photon number resolution of 61 by using the sandwich structure superconducting nanowires and multi wires working in parallel. The related rese...

The fully dielectric element surface has the characteristics of low material loss and strong field localization, making it very suitable for manipulating electromagnetic waves at the nanoscale. Especially the surface of all silicon dielectric elements can achieve ideal compatibility with complementary metal oxide semiconductor technology, making it an ideal choice for large-scale monolithic integr...
