1.3 μm InAs/GaAs quantum‐dot laser monolithically grown on Si substrates operating over 100°C
Siming Chen,Mingchu Tang,Jiang Wu,Qi Jiang,Vitaliy G. Dorogan,Mourad Benamara,Y.I. Mazur,Gregory J. Salamo,Alwyn J. Seeds,Huiyun Liu +9 more
TL;DR: In this paper, a 1.3 μm InAs/GaAs quantum-dot laser directly grown on Si substrates has been achieved by using InAlAs/GAAs strained-layer superlattice serving as dislocation filter layers (DFLs).
Journal ArticleDOI
InAs/GaAs Quantum-Dot Superluminescent Light-Emitting Diode Monolithically Grown on a Si Substrate
Siming Chen,Mingchu Tang,Qi Jiang,Jiang Wu,Vitaliy G. Dorogan,Mourad Benamara,Yuriy I. Mazur,Gregory J. Salamo,Peter Michael Smowton,Alwyn J. Seeds,Huiyun Liu +10 more
TL;DR: In this paper, the first superluminescent light-emitting diode (SLD) was constructed on a Si substrate and the two-section InAs/GaAs quantum-dot (QD) SLD produced a close-toGaussian emission spectrum of 114 nm centered at 1255 nm wavelength, with a maximum output power of 2.6 mW at room temperature.
Journal ArticleDOI
Optical injection locking and phase-lock loop combined systems.
TL;DR: This work has taken into account the modification of the slave laser phase response induced by the injection locking to calculated the phase-error signal spectrum and thephase-error variance for an optical injection locking and phase-lock system.
Journal ArticleDOI
High-Dynamic-Range Wireless-Over-Fiber Link Using Feedforward Linearization
TL;DR: In this article, the authors demonstrate the implementation of feedforward linearization at 5 GHz, which is the highest operating frequency yet reported, with 500-MHz linearization bandwidth having at least 24dB distortion suppression.
Journal ArticleDOI
Integration of III-V lasers on Si for Si photonics
Mingchu Tang,Jae Seong Park,Zhechao Wang,Siming Chen,Pamela Jurczak,Alwyn J. Seeds,Huiyun Liu +6 more
TL;DR: In this article, the authors review the latest developments on telecommunication wavelength III-V lasers integrated on Si substrates, in terms of integration methods and laser performance, and propose a monolithic and heterogeneous integration of IIIV semiconductor components on Si platforms.
