Yi Wang,Siming Chen,Ying Yu,Lidan Zhou,Lin Liu,Chunchuan Yang,Mengya Liao,Mingchu Tang,Zizhuo Liu,Jiang Wu,Wei Li,Ian M. Ross,Alwyn J. Seeds,Huiyun Liu,Siyuan Yu +14 more
TL;DR: In this paper, an electrically-pumped, room-temperature, continuous-wave (CW) and single-mode distributed feedback (DFB) laser array fabricated in InAs/GaAs quantum-dot (QD) gain material epitaxially grown on silicon is presented.
Journal ArticleDOI
Accurate equivalent circuit model for millimetre-wave UTC photodiodes.
Michele Natrella,Chin-Pang Liu,Chris Graham,Frederic van Dijk,Huiyun Liu,Cyril C. Renaud,Alwyn J. Seeds +6 more
TL;DR: It is shown that the measured impedance cannot be explained employing the standard junction-capacitance/series-resistance concept and a new model for the observed effects is proposed, which exhibits good agreement with the experimental data.
Journal ArticleDOI
Fast Tuneable InGaAsP DBR Laser Using Quantum-Confined Stark-Effect-Induced Refractive Index Change
Marianna Pantouvaki,Cyril C. Renaud,P. J. Cannard,Michael J. Robertson,Russell M. Gwilliam,Alwyn J. Seeds +5 more
TL;DR: In this paper, a monolithically integrated InGaAsP DBR ridge waveguide laser that uses the quantum-confined Stark effect (QCSE) to achieve fast tuning response was reported.
