We investigate and compare the intensity and polarization dynamics in a vertical-cavity surface-emitting laser (VCSEL) with a monolithically integrated, electrically controlled birefringence tuning mechanism. The influence of the bias current on the

Since the lasing operation of VCSELs results from the interplay of mechanisms belonging to different physical worlds, a realistic model should include electron and hole transport, optical and thermodynamic descriptions. In this context, it is possibl

Publikováno v: IEEE Journal of Quantum Electronics. 33:2240-2254

A comprehensive model is presented to study the electrical, thermal, and optical behavior of broad-area traveling-wave InGaAs-AlGaAs semiconductor amplifiers. Finite-element thermal analysis and carrier transport mechanisms are integrated into the be

Publikováno v: 2007 International Workshop on Optoelectronic Physics and Technology.

The new structure for management of carriers' ballistic transport have been proposed. This structure is based on effective-mass superlattice. The paper contains results which represent transmission coefficient spectra corresponding to center and non-

Monolithically integrated transceiver chips for bidirectional optical interconnection

Autor: Manikandan Chandran, I. Kardosh, P. Gerlach, M. Stach, R. Michalzik, F. Rinaldi, S. Lorch, Hendrik Roscher

Publikováno v: SPIE Proceedings.

We report on the design, fabrication and test results of monolithically integrated transceiver chips consisting of GaAs metal-semiconductor-metal photodiodes and 850nm wavelength vertical-cavity surface-emitting lasers. These chips are well suited fo
