How to face the loss in plasmonics and metamaterials
Jacob B. Khurgin
Metal losses affect the performance of every plasmonic or metamaterial structure; dealing with them will determine the degree to which these structures will find practical applicat…
Ultimate limit of field confinement by surface plasmon polaritons
Jacob B Khurgin
We show that electric field confinement in surface plasmon polaritons propagating at the metal/dielectric interfaces enhances the loss due to Landau damping and which effectively l…
Multi-phonon-assisted absorption and emission in semiconductors and its potential for laser refrigeration
Jacob B Khurgin
Laser cooling of semiconductors has been an elusive goal for many years, and while attempts to cool the narrow gap semiconductors such as GaAs are yet to succeed, recently, net coo…
Electronic states, pseudo-spin, and transport in the zinc-blende quantum wells and wires with vanishing band gap
Jacob B. Khurgin, Igor Vurgaftman
We consider theoretically the electronic structure of quasi-two and quasi-one-dimensional heterostructures comprised of III-V and II-VI semiconductors such as InAs/GaInSb and HgCdT…
Graphene - a rather ordinary nonlinear optical material
Jacob B khurgin
An analytical expression for the nonlinear refractive index of graphene has been derived and used to obtain the performance metrics of third order nonlinear devices using graphene…
Model for quantum efficiency of guided mode plasmonic enhanced silicon Schottky detectors
Ilya Goykhman, Boris Desiatov, Joseph Shappir +2
Plasmonic enhanced Schottky detectors operating on the basis of the internal photoemission process are becoming an attractive choice for detecting photons with sub bandgap energy.…
