【Abstract】 Based on waveguiding mode theory and non paraxial vectorial moment theory, the beam quality of TE 00 mode propagating in GaAs/Al xGa 1-x As strip buried heterostructure semiconductor laser is investigated theoretically, and the emphasis is laid on the variational relation between the beam quality factor in the direction parallel to the junction plane M 2 y and the active layer width W. The results show that M 2 y fluctuates with the active layer width W, which is useful for the proper design of the active layer width.更多还原
