Abstract

In this paper, a Vertical-Cavity Surface-Emitting Laser (VCSEL) of double oxide-confined regions is introduced. A direct coupling theoretical model in quasi-three-dimension for the gain-wave guide VCSEL has been created. With the finite-difference method, self-consistent solutions for the Poisson, injected current density, carrier concentration, optical field and thermal conduction equations were realized to study the electrical, optical and thermal fields characteristics of VCSEL with double oxide-confined regions or single oxide-confined region. The calculated results show that the structure of double oxide-confined regions in VCSEL has improved greatly the characteristics of lasers, and it provides a method of reducing threshold current and controlling high-order modes.
