Recently, the Los Alamos National Laboratory (LANL) in the United States has developed a method for quantum light emitters, which stacks two different atomic thin materials together to achieve a light source that generates circularly polarized single photon streams. These light sources can also be used for various quantum information and communication applications.According to Han Htoon, a researc...

Typically, for lasers in optical communication systems, waveguide designs are used to achieve a single transverse mode. By adjusting the thickness of the surrounding area of the cladding layer and the etching depth of the ridge in the ridge waveguide device, a single mode device can be obtained. The importance of lasers is reflected in the following aspects:A chip without ridge waveguide design an...

Light has angular momentum properties. Circularly polarized or elliptically polarized beams carry spin angular momentum (SAM), while beams with helical phase wavefronts carry orbital angular momentum (OAM). During the interaction between light and particles, the transfer of angular momentum can generate optical torque, driving particles to rotate. Among them, the transfer of optical spin angular m...
