【Abstract】 In the framework of 6 band effecive mass theory, the quantum structure effects on the optical properties of In 0.53Ga 0.47 As/InP quantum wire and quantum well are studied. The results show that optical gain is improved for quantum wire. Optical anisotropy for quantum wire is also found. The results indicate that quantum wire improves the optical properties of laser.更多还原
