Grafted AlGaAs/GeSn Optical Pumping Laser Operating up to 130 K
Jie Zhou, Daniel Vincent, Sudip Acharya +16
Group IV GeSn double-heterostructure (DHS) lasers offer unique advantages of a direct bandgap and CMOS compatibility. However, further improvements in laser performance have been b…
Electrically Injected mid-infrared GeSn laser on Si operating at 140 K
Sudip Acharya, Hryhorii Stanchu, Rajesh Kumar +6
Owing to its true direct bandgap and tunable bandgap energies,GeSn alloys are increasingly attractive as gain media for mid-IR lasers that can be monolithically integrated on Si. D…
Optical spectroscopy of excitons in ReS2 monolayers grown by chemical vapor deposition
Solomon Ojo, Juwon Onasanya, Morad Benamara +2
Monolayers of ReS2 were grown by a chemical vapor deposition technique on SiO2/Si substrates and investigated at room temperature by using micro-Raman, micro-photoluminescence (PL)…
Study of SiGeSn/GeSn single quantum well towards high-performance all-group-IV optoelectronics
Grey Abernathy, Yiyin Zhou, Solomon Ojo +8
The recent progress on (Si)GeSn optoelectronic devices holds a great promising for photonic integration on the Si substrate. In parallel to the development of bulk devices, the (Si…
Electrically injected GeSn lasers with peak wavelength up to 2.7 micrometer at 90 K
Yiyin Zhou, Solomon Ojo, Yuanhao Miao +15
GeSn lasers enable monolithic integration of lasers on the Si platform using all-group-IV direct-bandgap materials. Although optically pumped GeSn lasers have made significant prog…
Electrically injected GeSn lasers on Si operating up to 100 K
Yiyin Zhou, Yuanhao Miao, Solomon Ojo +14
The significant progress of GeSn material development has enabled a feasible solution to the long-desired monolithically integrated lasers on the Si platform. While there are many…
