【Abstract】 The mode and the threshold current characteristics of planar stripe geometry DH lasers can be analyzed by two-dimensional waveguide model. In this paper, first, the mode of waveguide is determined by solving the field equation, then the analytic expressions of the threshold current density corresponding to various parameters, particularly the active layer thickness and the stripe width are obtained according to the relationship between the mode width and the gain, and the threshold equation.更多还原
