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…
Exfoliation energy, quasi-particle bandstructure, and excitonic properties of selenium and tellurium atomic chains
Eesha Andharia, Thaneshwor P. Kaloni, Gregory J. Salamo +3
Effects that are not captured by the generalized-gradient density-functional theory play a prominent effect on the structural binding, and on the electronic and optical properties…
Observation of Nondegenerate Two-Photon Gain in GaAs
Matthew Reichert, Arthur L. Smirl, Greg Salamo +2
Two-photon lasers require materials with large two-photon gain (2PG) coefficients and low linear and nonlinear losses. Our previous demonstration of large enhancement of two-photon…
Probing InAs quantum dot states with surface plasmon polaritons
Fernando W. de Alencar Sobreira, Yuriy I. Mazur, Xian Hu +2
When placed near a thin metallic film, excitons in a quantum dot (QD) decay into surface plasmon polaritons (SPPs), guided modes of light confined at the interface of the metal/die…
Advanced holographic nondestructive testing system for residual stress analysis
Anatoli Kniazkov, Yuri Onischenko, George Dovgalenko +2
The design and operating of a portable holographic interferometer for residual stress analysis by creating a small scratch along with a new mathematical algorithm of calculations a…
