Performance characteristics of low threshold current 1.25-μm type-II GaInAs/GaAsSb W-lasers for optical communications
Dominic A. Duffy, Igor P. Marko, Christian Fuchs +4
Type-II W-lasers have made an important contribution to the development of mid-infrared laser diodes. In this paper, we show that a similar approach can yield high performance lase…
Auger Recombination Coefficients in Type-I Mid-Infrared InGaAsSb Quantum Well Lasers
Timothy D. Eales, Igor P. Marko, Alfred R. Adams +3
From a systematic study of the threshold current density as a function of temperature and hydrostatic pressure, in conjunction with theoretical analysis of the gain and threshold c…
Theory and design of InGaAsBi mid-infrared semiconductor lasers: type-I quantum wells for emission beyond 3 m on InP substrates
Christopher A. Broderick, Wanshu Xiong, Stephen J. Sweeney +2
We present a theoretical analysis and optimisation of the properties and performance of mid-infrared semiconductor lasers based on the dilute bismide alloy InGaAs$_{1…
Valence band-anticrossing in GaPBi dilute bismide alloys: giant bowing of the band gap and spin-orbit splitting energy
Zoe L. Bushell, Christopher A. Broderick, Lukas Nattermann +5
Using spectroscopic ellipsometry measurements on GaPBi/GaP epitaxial layers up to % we observe a giant bowing of the direct band gap () and valence…
High-Q photonic crystal cavities in all-semiconductor photonic-crystal heterostructures
Zoe Bushell, Marian Florescu, Stephen Sweeney
Photonic crystal cavities enable the realization of high Q-factor and low mode-volume resonators, with typical architectures consisting of a thin suspended periodically-patterned l…
Impact of alloy disorder on the band structure of compressively strained GaBiAs
Muhammad Usman, Christopher A. Broderick, Zahida Batool +4
The incorporation of bismuth (Bi) in GaAs results in a large reduction of the band gap energy (E) accompanied with a large increase in the spin-orbit splitting energy ($\bigtri…
