Crosslight is pround to announce a technical breakthrough in the device modeling of semiconductor optoelectronic devices: 2/3D simulation of microcavity laser diodes. The new modeling abandons the traditional approach of separating solutions of longitudinal and lateral modes and solves the Maxwell wave equations in all directions rigorously for all eigen modes operating at different wavelengths.

The microcavity option of PICS3D finds applications in VCSEL, RCLED, QD-LD/QD-LED, and microdisk lasers, where optical modes couple in different directions. A demonstration of the model as applied to surface relief VCSELs may be found in this presentation.
