Abstract

We fabricated and investigated two confocal quasi-stadium laser diodes: one has a narrow electrode contact pattern along its cavity axis and the other has a narrow electrode contact pattern along a diamond-shaped trajectory. The lowest-order axial and ring modes were selectively excited. The resonator modes of the laser diodes were calculated using the extended Fox-Li mode calculation method. Although some deformation of the far-field emission pattern was observed in experiments, the numerically calculated far-field emission patterns agree well with the experimentally observed far-field patterns.
