Abstract

General scaling laws for gain-guided vertical cavity lasers with distributed Bragg reflectors are introduced. The validity of these laws is verified using a self-consistent calculation of transverse modes and propagation constants for two-dimensional laser cavities. The definition of Fresnel number is generalized to cavities with distributed mirrors. We show that all of the resonator parameters—the threshold gain, the frequency spectrum, and the transverse mode patterns scale with the ratio between the Fresnel number and the cold cavity finesse.
