Abstract :
We report a numerical analysis on the transverse mode behavior of a novel passive antiguide region buried heterostructure vertical cavity surface emitting laser, which emits a single stable transverse mode from a large aperture. Two- and three-dimensional beam propagation methods were used to calculate the threshold gains and the actual modal profiles for the fundamental and first order modes. We show that the passive antiguide structure is the main modal selection mechanism and the high order modes suffer much higher losses such that they are highly suppressed from reaching thresholds.<>
