Threshold Gain Calculations for Vertical-Cavity Surface-Emitting Lasers (VCSELs)

Application ID: 88861

An eigenfrequency study is used to find the resonance frequency and threshold gain for an oxide-confined, GaAs-based, vertical-cavity surface-emitting laser (VCSEL).

The simulations are performed in two steps. A regular eigenfrequency analysis is first performed, to find good initial values for the subsequent nonlinear eigenfrequency analysis.

The resonance frequencies and threshold gain, calculated for different device geometries, compare well to values from a paper collecting the results from different computational methods on this benchmark problem.

This model example illustrates applications of this type that would nominally be built using the following products:
