On-chip integrated, silicon-graphene plasmonic Schottky photodetector, with high responsivity and avalanche photogain
Ilya Goykhman, Ugo Sassi, Boris Desiatov +8
We report an on-chip integrated metal-graphene-silicon plasmonic Schottky photodetector with 85mA/W responsivity at 1.55 um and 7% internal quantum efficiency. This is one order of…
Enhancement of Two-photon Absorption in Quantum Wells for Extremely Nondegenerate Photon Pairs
Himansu S. Pattanaik, Matthew Reichert, Jacob B. Khurgin +2
We recently demonstrated orders of magnitude enhancement of two-photon absorption (2PA) in direct gap semiconductors due to intermediate state resonance enhancement for photons of…
Impact of surface collisions on enhancement and quenching of the luminescence near the metal nanoparticles
Jacob B Khurgin, Greg Sun
The fact that surface-induced damping rate of surface plasmon polaritons (SPPs) in metal nanoparticles increases with the decrease of particle size is well known. We show that this…
On the Origin of the Second-Order Nonlinearity in Strained Si-SiN Structures
Jacob B. Khurgin, Todd H. Stievater, Marcel W. Pruessner +1
The development of efficient low-loss electro-optic and nonlinear components based on silicon or its related compounds, such as nitrides and oxides, is expected to dramatically enh…
Density-Dependent Electron Transport and Precise Modeling of GaN HEMTs
Sanyam Bajaj, Omor F. Shoron, Pil Sung Park +7
We report on the direct measurement of two-dimensional sheet charge density dependence of electron transport in AlGaN/GaN high electron mobility transistors. Pulsed IV measurements…
Two-dimensional exciton-polariton - light guiding by transition metal dichalcogenide monolayers
Jacob B. Khurgin
A monolayer of transition metal dichalcogenide (TMDC) is shown to be capable of supporting a guided optical mode below the exciton resonance, a two-dimensional exciton polariton. T…
Prospects and merits of metal-clad semiconductor lasers from nearly UV to far IR
Jacob B. Khurgin
Using metal-clad (or plasmonic) waveguide structures in semiconductor lasers carries a promise of reduced size, threshold, and power consumption. This promise is put to a rigorous…
