Modern laser technology urgently requires nonlinear optical materials that can generate coherent light through second harmonic generation. However, only a small portion of the nonlinear optical properties of non centrosymmetric crystal materials have been experimentally or theoretically studied, and exploration for high-performance nonlinear optical crystal materials is still very limited.Recentl...
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...
