A new scheme for direct and tunable (30nm shown here) QAM synthesis from binary RF data streams is demonstrated with up to 48Gbit/s QPSK, including propagation over 75km SMF-28. Preliminary 16QAM (60G...
The investigation of the nonlinear dynamics of a semiconductor laser based on nonlinear optical loop mirror (NOLM) feedback using Ge doped optical fiber was carried out experimentally. Animations of c...
A phase preserving limiter based on injection locking in semiconductor lasers is experimentally investigated for 10Gb/s phase encoded signals. The proposed scheme exhibits significant amplitude noise ...
Preface to Topical Papers on Direct Applications of High-Power Semiconductor Lasers.
A technology of high power, continuous-wave (CW) semiconductor lasers has been elaborated. AlGaAs/InGaAs/GaAs heterostructures, grown by molecular beam epitaxy (MBE), were used to fabricate laser diod...
We have developed a new technique for monitoring the facet heating in semiconductor lasers and for correlating these measurements with the performance and reliability of the device. The method is base...
The paper deals with selected problems of molecular beam epitaxy (MBE) technology of fabrication of 980-nm strained InGaAs quantum-well (QW) lasers. Special attention has been paid to the growth of ac...
Broad-area InGaAs-AlGaAs laser diodes emitting at a wavelength of 980 nm with dry-etched mirror facets are presented. The devices exhibit optical output powers up to 1.5W per facet at room temperature...
Some aspects on coherent feedback in a laser diode are investigated. In particular, weak optical feedback is considered in the context of the feedback-induced frequency shift. In addition, the Lang-Ko...
