This past wednesday both Tristan and Sid presented at the University of Iowa Spring Undergraduate Research Festival, on their work which is being performed as part of their shared ICRU fellowship. Congratulations on a great presentation!

Perspective on anisotropy in nanophotonics published in ACS Photonics

Publication reviews the possibilities for low symmetry materials for next generation nanophotonics.

Perspective on new concepts for infrared optoelectronics

Here we discuss how a new generation of infrared optoelectronics could be realized leveraging surface phonon polaritons.

Research on Hyperbolic Shear Polaritons published in Nature

Shear phenomena in the infrared dielectric response of a monoclinic crystal are shown to unveil a new polariton class termed hyperbolic shear polariton that can emerge in any low-symmetry monoclinic or triclinic system

Hybrid Mid-Near Infrared Waveguides

In recent work published in Advanced Materials, us and collaborators at Vanderbilt show that both near infrared and mid-infrared light can be guided on a silicon chip by combining two different materials
