CLEO/Europe. 2005 Conference on Lasers and Electro-Optics Europe, 2005..
Distributed feedback lasers (DFBs) monolithically integrated with electroabsorption modulators (EAMs) are considered as key components for modern optical telecommunication systems due to very high speed operation capability. Investigated devices are

Proceedings IEEE/WIC International Conference on Web Intelligence (WI 2003).
We present detailed theoretical and experimental investigations on gain and absorption spectra of multi-type AlGaInAs QW structures in the 1.3 /spl mu/m wavelength regime. Such QW combination offer the possibility of efficient forward and reverse ope

SPIE Proceedings.
We compare various approaches aiming at large-area high-power single-mode oxidized VCSELs. Stable and reproducible single-mode emission with SMSR (side-mode suppression ratio) greater than 30dB and output powers well above 5mW are reported for the lo

Vertical-Cavity Surface-Emitting Lasers V.
We present top surface emitting two- and three-stage bipolar cascade vertical cavity surface emitting lasers (VCSELs) for continuous wave (cw) operation at room temperature. The results are compared with a conventional VCSEL grown under identical gro
