Abstract :
In this paper, the loss of a simplified cavity is studied using an accurate numerical model that solves the scalar Helmholtz Equation at each point in the cavity. The idealized cavity geometry consists of two perfect mirrors. The upper mirror is offset inward at some radius as shown, so that the cavity is laterally index guided. A cavity length was chosen to mimic (approximately) the number of standing waves in a vertical cavity surface emitting laser (VCSEL) cavity, including the distributed Bragg mirrors.
