Abstract

In this talk, I will introduce MoO3 as an anisotropic photonic and polaritonic material. MoO3 is a layered material that exhibits both in and out-of-the-plane anisotropic polaritonic response at mid-IR wavelengths. We designed and experimentally demonstrated an anisotropic polaritonic absorber and showed that one can couple to all phonon modes and address them individually either using structural tunability or polarization control of incident infrared radiation. I will also discuss our experimental investigations of the birefringent optical properties of MoO3 in visible frequencies. By constructing MoO3 based Fabry-Perot resonator, we observed strong polarization-dependent tunability of the Fabry-Perot resonance due to different refractive index of MoO3 for different crystal directions.
