Multi-frequency coherent emission from superstructure thermal emitters
Guanyu Lu, Marko Tadjer, Joshua D. Caldwell +1
Long-range spatial coherence can be induced in thermal emitters by embedding a periodic grating into a material supporting propagating polaritons or dielectric modes. However, the…
Plasmonically-Enhanced Emission from an Inverted GaN Light Emitting Diode
Michael A. Mastro, Byung-Jae Kim, J. A. Freitas +5
Silver nanoparticles dispersed on the surface of an inverted GaN LED were found to plasmonically enhance the near-bandedge emission. The resonant surface plasmon coupling led to a…
Design of Gallium Nitride Resonant Cavity Light Emitting Diodes on Si Substrates
Michael A. Mastro, Joshua D. Caldwell, Ron T. Holm +2
A GaN resonant cavity light emitting diode was built on a GaN-AlN distributed Bragg reflector grown on a silicon substrate. The electroluminescence output increased by 2.5 times fo…
Guided Mid-IR and Near-IR Light within a Hybrid Hyperbolic-Material/Silicon Waveguide Heterostructure
Mingze He, Sami I. Halimi, Thomas G. Folland +6
Silicon waveguides have enabled large-scale manipulation and processing of near-infrared optical signals on chip. Yet, expanding the bandwidth of guided waves to other frequencies…
Lithography-free IR polarization converters via orthogonal in-plane phonons in a-MoO3 flakes
Sina Abedini Dereshgi, Thomas G. Folland, Akshay A. Murthy +5
Exploiting polaritons in natural vdW materials has been successful in achieving extreme light confinement and low-loss optical devices and enabling simplified device integration. R…
Long-lived modulation of plasmonic absorption by ballistic thermal injection
John A. Tomko, Evan L. Runnerstrom, Yi-Siang Wang +9
Energy and charge transfer across metal-semiconductor interfaces are the fundamental driving forces for a broad range of applications, such as computing, energy harvesting, and pho…
