However, current state of the art IR devices are plagued by bulky components, low efficiency, and low robustness. In response, IR nanophotonics have garnered strong interest for next generation devices. The most promising approaches for IR nanophotonics involve coupling light to free carriers in metals and doped semiconductors (plasmon polaritons), or to lattice vibrations of polar crystals (phonon polaritons). Plasmon polaritons offer broad tunability with low efficiency, and phonon polaritons offer high efficiency with low tunability. The work presented here focuses on phonon polaritons in low symmetry crystals, which have been shown to offer remarkable control over the confinement and propagation of light at scales much smaller than the optical wavelengths. In particular, we study the phonon polaritons of uniaxial, biaxial, and monoclinic systems \u2013 demonstrating ultrafast control, refractive polariton optics, tunable beam-steering, and broken symmetry propagation in natural crystals. We also explore the design of phonon energies through atomic-scale structuring of superlattices \u2013 stacks of alternating crystal layers. The results provide promising new paths for IR nanophotonic devices.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>DISSERTATION DEFENSE Joseph Matson,\u00a0Interdisciplinary Materials Science *under the direction of Dr. Josh Caldwell \u201cGaining Nanophotonic Control through Crystalline Anisotropy\u201d 12.05.22 | 3:00pm CST |\u00a0048\u00a0Engineering Science Building\u00a0 |\u00a0 Zoom Infrared (IR) optics form the basis for many important applications, including chemical spectroscopy for pharmaceuticals, medical testing, environmental monitoring, automotives, and aerospace, to name a few.
