High Power High Beam Quality 1060-nm Large Optical Cavity Asymmetric Waveguide Semiconductor Laser Diode

Study on the effect of double-trench ridge waveguide structure on output characteristics of semiconductor FP laser

“…With the continuous improvement of the transmission distance and stability requirements of modern optical communication, people have put forward higher requirements for the stability of the fundamental transverse mode of the laser. With the development of molecular beam epitaxy [1] (MBE), metal-organic chemical vapor deposition [2] (MOCVD) and other technologies, researchers at home and abroad have proposed multi-quantum well structure [3] , planar coupling waveguide [4] , photonic crystal structure [5] , asymmetric large optical cavity [6] and other structures. These structures can make the laser obtain more stable mode output in the transverse direction perpendicular to the junction plane.…”
