Lateral mode discrimination in surface emitting DBR lasers with cylindrical symmetry

The effective reflectivity and the threshold gain of all lateral modes in a surface emitting DBR laser with cylindrical symmetry are analyzed using the coupled-mode approach. Our results indicate that when a cavity is designed for operation in the odd modes, all even modes are effectively eliminated...

Summary:The effective reflectivity and the threshold gain of all lateral modes in a surface emitting DBR laser with cylindrical symmetry are analyzed using the coupled-mode approach. Our results indicate that when a cavity is designed for operation in the odd modes, all even modes are effectively eliminated. A small perturbation is introduced into the complex dielectric constant of the active region to suppress the unwanted lateral modes of odd symmetry. The model predicts that lasing will occur in a single mode with a narrow far-field pattern.< >
