The lattice constant of a single-defect photonic crystal vertical-cavity surface-emitting laser (PhC-VCSEL) is numerically optimized to achieve the highest single-mode power in the fundamental mode. The simulated results are compared to measured device characteristics, and the different factors influencing the single-mode behavior are analyzed.
Thermal lens effect on single-transverse-mode stability of proton-implanted photonic-crystal vertical-cavity surface-emitting lasers is studied. Theoretical and experimental demonstration of the trade-off between the single-mode stability and low loss. Single-mode stability with a smaller lattice constant is also discussed.
The polarization-resolved optical modes of three-dimensional vertical-cavity surface-emitting lasers are calculated. The Helmholtz-equation is discretized on prism elements, and the resulting eigenproblem is solved by an efficient numerical technique. The full vectorial treatment enables one to determine the polarization characteristics of these lasers.
The electromagnetic problem of modeling vertical-cavity surface-emitting lasers with their full 3D structure is analyzed. The vectorial Helmholtz equation is discretized on prism elements, and the resulting complex symmetric generalized eigen- problem is solved by an efficient numerical technique. The full-vectorial treatment enables one to determine the polarization characteristics of these lasers...
