TL;DR: In this article, a wideband (370?2500MHz) distributed antenna system (DAS) which uses pluggable analogue optical transceivers based on the industry standard small form-factor (SFP) format is presented.

TL;DR: In this article, the authors present a modeling tool for the numerical evaluation of antenna coupled uni-travelling carrier photodiodes and experimental evaluation of the fabricated designs.

TL;DR: In this paper, the authors present an approach to modeling III-V lasers on silicon based on a travelling-wave rate equation model with sub-micrometer resolution by allowing spatially resolved inclusion of individual dislocations along the laser cavity, which offers new insights into the physical mechanisms behind the characteristics of 980nm In(Ga)As/GaAs quantum well (QW) and 1.3μm quantum dot (QD) lasers grown on silicon.

TL;DR: A continuously tunable optical frequency comb generator (OFCG), with comb lines spanning over 3.8 THz which, to the best of the authors' knowledge, is the widest span yet reported for a single-phase modulator OFCG system.

TL;DR: The first InGaAsP-based uni-travelling carrier photodiode structure grown by Solid Source Molecular Beam Epitaxy is reported, which gives the benefit of the superior control provided by MBE growth techniques without the costs and the risks of handling toxic gases.
