An improved time-domain traveling-wave model for vertical-cavitysurface-emitting lasers

摘要

The use of the time-dependent transfer matrix and wide-angle beamnpropagation method is proposed to improve the computational speed andnaccuracy of a recently developed time-domain traveling-wave model ofnvertical-cavity surface-emitting lasers. With suitable utilization ofnthe transfer matrix, significant reduction of the total execution timenof the traveling-wave model can be obtained. In addition, the use of thenwide-angle beam propagation method can minimize the calculation error ofnthe traveling-wave model due to the diffraction of light from the smallnaperture of the laser cavity
