Photonic spin and chirality in subwavelength optical cavities
Abstract/Contents
- Abstract
- Spin symmetry is fundamental to matter: from the handedness of DNA and amino acids to the angular momentum of electrons. Since the mid-nineteenth century, light has been our probe of spin typically via the weak preferential absorption of circularly polarized light. However, as we approach smaller lengths scales, especially smaller than the wavelength of light, interactions become several orders of magnitude weaker, and we struggle to resolve our observations. Magnifying these otherwise weak interactions while controlling the spin symmetry of the interaction will enable us to better direct light, create quantum bits of information for exponentially faster computing, and communicate information at light-speeds. In this dissertation, we present: 1) symmetry-protected optical cavities that magnify the local electromagnetic energy density, 2) the spin dissymmetry factor as a parameter to describe the interaction of light with quantum particles in optical cavities, and 3) the design of a highly asymmetric optical cavity that imparts one-way spin for complete control (isolation) over lasing. These optical cavities are designed with complete control over three-dimensional symmetry using dielectric metasurfaces.
