Passband filters for terahertz radiation based on dual metallic photonic structures (2007)
Journal Article
Gallant, A., Kaliteevski, M., Wood, D., Petty, M., Abram, R., Brand, S., …Chamberlain, J. (2007). Passband filters for terahertz radiation based on dual metallic photonic structures. Applied Physics Letters, 91(16), https://doi.org/10.1063/1.2800381

This paper reports on the development of two-dimensional metallic microstructures for the filtering of terahertz radiation. These structures are fabricated using ultraviolet-based processing of thick SU8 resist. This micromachining technique enables...

Tamm plasmon-polaritons: Possible electromagnetic states at the interface of a metal and a dielectric Bragg mirror (2007)
Journal Article

Conventional surface plasmons have a wave vector exceeding that of light in vacuum, and therefore cannot be directly excited by light that is simply incident on the surface. However, we propose that a plasmon-polariton state can be formed at the boun...

Density of states of a one-dimensional disordered photonic crystal (2007)
Journal Article

An analytic theory of the density of states in one-dimensional disordered photonic crystals is proposed. It is shown that the problem of the density of optical modes can be reduced in the small dielectric contrast approximation to solving a generaliz...

Terahertz Frequency Bandpass Filters (2007)
Journal Article

The design, measurement, and analysis of a range of artificial materials for use at terahertz frequencies are described. The chosen structures consist of arrays of cylindrical gold-plated pillars with period comparable to the wavelength of incident r... Read More about Terahertz Frequency Bandpass Filters.

Whispering gallery polaritons in cylindrical cavities (2007)
Journal Article
Kaliteevski, M., Brand, S., Abram, R., Kavokin, A., & Dang, L. S. (2007). Whispering gallery polaritons in cylindrical cavities. Physical review B, 75(23), https://doi.org/10.1103/physrevb.75.233309

Strong coupling of the whispering gallery modes with bulk excitons in semiconductor cylinders is demonstrated theoretically. The strong-coupling threshold is governed by the radiative decay rate of optical modes, which we analyze as a function of the...

It is now well established that two-dimensional structures with dielectric variations based on quasicrystalline tilings are able to support photonic band gaps. Here, we have investigated the properties of the localized defect modes with frequencies w...

Dynamics of a nonlinear ring cavity: Excitability and coherent resonance (2007)
Journal Article

The phenomena of excitability and coherent resonance in a nonlinear ring cavity in the presence of excitons and biexcitons are considered. A bifurcation analysis of the dynamics of the nonlinear ring cavity indicates that both self-pulsation and exci...

Tamm states of light are localized interface modes inside the light-cone. In contrast to the surface modes they can have a zero in-plane wave-vector. We show that they can be formed in both TE and TM polarizations at the boundary between the isotropi...
