Negative refraction and the spectral filtering of terahertz radiation by a photonic crystal prism (2011)
Journal Article
Swift, G., Gallant, A., Kaliteevskaya, N., Kaliteevski, M., Brand, S., Dai, D., Baragwanath, A., Iorsh, I., Abram, R., & Chamberlain, J. (2011). Negative refraction and the spectral filtering of terahertz radiation by a photonic crystal prism. Optics Letters, 36(9), 1641-1643. https://doi.org/10.1364/ol.36.001641

We demonstrate how micromachined photonic crystals can be used to negatively refract terahertz frequency light. The photonic crystals, which are constructed from conventional dielectric materials, manipulate the incident beam via interaction with the...

Self-catalyzed, pure zincblende GaAs nanowires grown on Si(111) by molecular beam epitaxy (2010)
Journal Article
Cirlin, G., Dubrovskii, V., Samsonenko, Y., Bouravleuv, A., Durose, K., Proskruryakov, Y., Mendes, B., Bowen, L., Kaliteevski, M., Abram, R., & Zeze, D. (2010). Self-catalyzed, pure zincblende GaAs nanowires grown on Si(111) by molecular beam epitaxy. Physical review B - Condensed Matter and Materials Physics, 82(3), Article 035302. https://doi.org/10.1103/physrevb.82.035302

We report on the Au-free molecular beam epitaxy growth of coherent GaAs nanowires directly on Si(111) substrates. The growth is catalyzed by liquid Ga droplets formed in the openings of a native oxide layer at the initial growth stage. Transmission e...

Negative refraction can make non-diffracting beams (2008)
Journal Article
Kaliteevski, A., Brand, S., Abram, R., Gallant, A., & Chamberlain, J. (2008). Negative refraction can make non-diffracting beams. Optics Express, 16(19), 14582-14587. https://doi.org/10.1364/oe.16.014582

We report the results of simulations relating to the illumination of a structure consisting of a slab constructed from a 2-D hexagonal array of metal rods with a terahertz frequency source. As a consequence of negative refraction an essentially non-d... Read More about Negative refraction can make non-diffracting beams.

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...

Terahertz Frequency Bandpass Filters (2007)
Journal Article
Gallant, A., Kaliteevski, M., Brand, S., Wood, D., Petty, M., Abram, R., & Chamberlain, J. (2007). Terahertz Frequency Bandpass Filters. Journal of Applied Physics, 102(2), https://doi.org/10.1063/1.2756072

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.
