Check out our inverse design work on Tamm plasmon thermal emitters!
Oct. 21, 2021—Our recent work on inversely designed Tamm plasma polariton thermal emitters was just published in Nature Materials, and it is also on the research news of the School of Engineering! With stochastic gradient descent, we are able to inversely design the Tamm plasma devices with numerous changeable parameters within several minutes on a consumer-grade desktop. Additionally,...
Check out our superstructure grating work!
Apr. 8, 2021—Our recent superstructure grating work just published in Applied Physics Letters! We demonstrated multiple coherent emission modes at different combinations of frequency and angle, controlled by the superstructure design. These superstructure gratings can be used to tailor the thermal emission of polaritonic thermal emitters. We also suggest the coherence length can be used as an appropriate...

Check out our recent work on guided mid-and near-IR paper!
Mar. 4, 2021—Our recent work on guided mid- and near-IR light in a hybrid system just published in Advanced Materials, and it is also on the research news of the School of Engineering! With hyperbolic phonon polaritons supported by hexagonal boron nitride, the mid-IR light is confined to a small length scale, and guided along a silicon waveguide underneath...
Check out our recent work on thermal emission engineering!
Feb. 16, 2021—Our recent work on thermal emission engineering just published in Nano Letters. By leveraging three-oscillator strong coupling, the spectral and spatial dispersion of thermal emission can be engineered for a variety of IR applications. We demonstrated a five-fold improvement in the spatial coherence and a three-fold enhancement of the quality factor of the mixed polaritonic...
Demonstration of nanophotonic IR emitting metamaterials for gas sensing!
Jan. 14, 2021—Congratulations to our former VINSE REU student Alyssa Livingood and a senior graduate student in IMS Ryan Nolen for leading the charge in demonstrating the use of cadmium oxide films for a narrowband, normal incidence nanophotonic IR emitting metamaterial (NIREM). Through a collaboration with Third Floor Materials, it was demonstrated that the radiation pattern could...
See our work with the Abate group on the IR response of Mica
Jan. 14, 2021—Check out our recent collaborative work with Yohannes Abate’s group at the University of Georgia looking at the near-field IR response of mica.
Collaborative work demonstrating ultrastrong coupling in the mid-infrared published in Nature Photonics!
Dec. 9, 2020—Check out the recent publication in Nature Photonics highlighting ultrastrong coupling between vibrational modes and plasmon polaritons. Achieved with an optical analog of a coaxial cable, this was achieved by funneling infrared light with a wavelength almost 3000 times larger than the 3-nm wide SiO2 apertures. Also see the highlight of this work from Vanderbilt.
