The tunnel junction is literally confined forming an aperture for current injection and wave guiding. A self-consistent VCSEL simulation software is employed in order to analyze and optimize the internal device physics.","PeriodicalId":206987,"journal":{"name":"IEEE/LEOS 3rd International Conference on Numerical Simulation of Semiconductor Optoelectronic Devices, 2003.

A valence-force-field method is used for the strain distribution, and a finite-difference method for the polarization-induced potential and field. We find that a strong built-in electric field is induced in the QDs due to the polarization. The field causes the quantum-confined Stark effect in the QDs; i.e., red-shifted transition energies and a spatial separation of electron and hole wave functions.","PeriodicalId":206987,"journal":{"name":"IEEE/LEOS 3rd International Conference on Numerical Simulation of Semiconductor Optoelectronic Devices, 2003.

There are many challenges that await technical innovations to make these modules competitive with much higher end software currently available commercially. Our initial emphasis has been on the modeling of nonlinear optical phenomena that advanced devices rely on as well as nonlinear optical processes one may want to control in such semiconductor laser devices for telecom and homeland security applications. We have also modeled superprisms and photonic band gap structures. A comprehensive semiconductor laser diode model is being constructed and tested against experimental data so that gain modeling, carrier, heat and photon transport can all be combined in a predictive module. Wavelets can help choose optimum meshes that are dynamically adapted to capture nonlinear steepening and field concentrations that change over the course of one simulation. Finite element techniques are well suited for static non-uniformities. Finite elements and wavelets are thus seen to play complementary and mutually reinforcing roles.","PeriodicalId":206987,"journal":{"name":"IEEE/LEOS 3rd International Conference on Numerical Simulation of Semiconductor Optoelectronic Devices, 2003.

Strained Q-wire lasers with SC barriers and a cavity normal to wire axis should provide minimum transparency carrier density. In moderately wide Q-wires, highest peak material gain is obtained with lattice-matched barriers when the cavity is parallel to the wire axis. Polarization dependence of the gain in the presence of elastic strain relaxation shows non-trivial dependence on wire width due to a complicated interaction between elastic strain relaxation and quantum size effects.","PeriodicalId":206987,"journal":{"name":"IEEE/LEOS 3rd International Conference on Numerical Simulation of Semiconductor Optoelectronic Devices, 2003.

It is shown that the ZnO hexagonal microtubes have demonstrated ultraviolet (/spl sim/393 nm) lasing emission under 355 nm optical excitation. Furthermore, the lasing as well as modal characteristics of the microtube lasers are investigated theoretically. It can be explained that the high threshold pump intensity of the microtube lasers is due to high radiation loss near the prismatic facets. In addition, our calculation has shown that the output beam from the microtube lasers has a shape similar to the doughnut ring, which can find application as laser tweezers to trap low refractive index small particles.","PeriodicalId":206987,"journal":{"name":"IEEE/LEOS 3rd International Conference on Numerical Simulation of Semiconductor Optoelectronic Devices, 2003.
