Modeling of a Vertical Cavity Surface Emitting Laser with a Resonant Array of Quantum Wells
- Conference date: 18–22 September 2009
- Location: Rethymno, Crete (Greece)
The 3D numerical model of a vertical cavity surface emitting laser (VCSEL) containing a resonant heterostructure of an array of quantum wells (QW) is proposed. We have for an object the self‐consistent solution of the electromagnetic field equations and the active medium equations. The wave field profile and frequency of a lasing mode are found from the eigenvalue problem for a non‐linear operator specially adapted. The stability of single‐mode operation is determined from the linear non‐hermitian eigenproblem when the active medium characteristics are established by a lasing mode and “frozen.” Complex eigenvalues found define the losses and exact wavelengths of higher‐order modes. The results of calculations for a cylindrical VCSEL with e‐beam pumping will be reported.
