Investigation of 2D laterally dispersive photonic crystal structures : LDRD 33602 final report

Vawter, Gregory A.; Peters, D.W.; Wendt, J.R.; Hadley, G.R.; Vawter, Gregory A.; Peake, Gregory M.; Guo, Junpeng; Subramania, Ganapathi S.

Artificially structured photonic lattice materials are commonly investigated for their unique ability to block and guide light. However, an exciting aspect of photonic lattices which has received relatively little attention is the extremely high refractive index dispersion within the range of frequencies capable of propagating within the photonic lattice material. In fact, it has been proposed that a negative refractive index may be realized with the correct photonic lattice configuration. This report summarizes our investigation, both numerically and experimentally, into the design and performance of such photonic lattice materials intended to optimize the dispersion of refractive index in order to realize new classes of photonic devices.

Turning the microcavity resonant wavelength in a 2D photonic crystal by modifying the cavity geometry

Proposed for publication in Applied Physics Letters.

Subramania, Ganapathi S.; Lin, Shung W.; Wendt, J.R.; Rivera, Jonathan M.

High-quality-factor microcavities in two-dimensional photonic crystals at optical frequencies have a number of technological applications, such as cavity quantum electrodynamics, optical switching, filtering, and wavelength multiplexing. For such applications, it is useful to have a simple approach to tune the microcavity resonant wavelength. In this letter, we propose a microcavity design by which we can tune the resonant wavelength by changing the cavity geometry while still obtaining a high quality factor.
