Controlling the dopant profile for SRH suppression at low current densities in 1330nm GaInAsP light-emitting diodes
Parthiban Santhanam, Wei Li, Bo Zhao +5
The quantum efficiency of double hetero-junction light-emitting diodes (LEDs) can be significantly enhanced at low current density by tailoring the spatial profile of dopants to su…
Low-Temperature Annihilation Rate for Quasi-Localized Excitons in Monolayer MoS2
Eric Chatterjee, Daniel B. S. Soh, Christopher Rogers +2
The strong Coulomb forces in monolayer transition metal dichalcogenides ensure that optical excitation of band electrons gives rise to Wannier-Mott excitonic states, each of which…
Coherent Control of Two-Dimensional Excitons
Christopher Rogers, Dodd Gray, Nathan Bogdanowicz +3
Electric dipole radiation can be controlled by coherent optical feedback, as has previously been studied by modulating the photonic environment for point dipoles placed both in opt…
Laser Annealing for Radiatively Broadened MoSe2 grown by Chemical Vapor Deposition
Christopher Rogers, Dodd Gray, Nate Bogdanowicz +1
We report on a laser annealing procedure which greatly improves the quality of suspended monolayers of chemical vapor deposition (CVD) grown MoSe2. Annealing with a green laser loc…
Conditions for Parametric and Free-Carrier Oscillation in Silicon Ring Cavities
Ryan Hamerly, Dodd Gray, Christopher Rogers +1
We model optical parametric oscillation in ring cavities with two-photon absorption, focusing on silicon at 1.55m. Oscillation is possible if free-carrier absorption can be miti…
Optical nonlinearities of excitons in monolayer MoS2
Daniel B. S. Soh, Christopher Rogers, Dodd J. Gray +2
We calculate linear and nonlinear optical susceptibilities arising from the excitonic states of mono- layer MoS2 for in-plane light polarizations, using second-quantized bound and…
