Vertical-cavity surface-emitting lasers (VCSELs) have become leading light sources in plenty of applications due to their good characteristics and low costs. There are, however, some features that need improvements; therefore, optimized or new design

We present a comprehensive fully vectorial model for the cavity eigenmodes of oxide-confined vertical-cavity surface-emitting lasers (VCSELs) with the details of their complex structure. It includes device-inherent symmetry-breaking mechanisms like n

Publikováno v: IEEE Journal of Quantum Electronics. 37:1084-1094

We present a model to compute the linewidth in vertical-cavity surface-emitting lasers (VCSELs), by accounting for the 3-D structure of real devices. To this aim, we include the noise source in the field equations and treat both the noise and the str

Optical bistability in a multiple-quantum-well structure with Fabry-Pérot and distributed-feedback resonators

Autor: F. Castelli, Gian Paolo Bava, Pierluigi Debernardi, Luigi A. Lugiato

Publikováno v: Physical Review A. 45:5180-5192

The system we analyze has the structure of a planar optical waveguide containing a multiple quantum well, with the planes of the wells parallel to the direction of propagation. We consider the two different configurations of a Fabry-P\'erot cavity an

Within a joint collaboration between modeling, technology and experiments, we investigate the polarization-resolved spatial emission and turn-on dynamics of oxide-confined vertical-cavity surface-emitting lasers with an integrated surface-relief grat
