Efficient out-coupling and beaming of Tamm optical states via surface plasmon polariton excitation (2014)
Journal Article
Lopez-Garcia, M., Ho, Y. -. D., Taverne, M. P. C., Chen, L., Murshidy, M. M., Edwards, A. P., …Oulton, R. (2014). Efficient out-coupling and beaming of Tamm optical states via surface plasmon polariton excitation. Applied physics letters, 104(23), 231116. doi:10.1063/1.4882180

We present evidence of optical Tamm states to surface plasmon polariton (SPP) coupling. We experimentally demonstrate that for a Bragg stack with a thin metal layer on the surface, hybrid Tamm-SPP modes may be excited when a grating on the air-metal... Read More

Light emission enhancement using randomly distributed plasmonic nanoparticle arrays (2014)
Journal Article
Butkus, J., Edwards, A. P., Quacquarelli, F. P., & Adawi, A. M. (2014). Light emission enhancement using randomly distributed plasmonic nanoparticle arrays. Optical materials, 36(9), 1502-1505. doi:10.1016/j.optmat.2014.04.010

We have fabricated and characterised the optical properties of solution processed randomly distributed gold nanoparticle plasmonic arrays that are coated with a thin-film fluorescent dye. Three times enhancement in the emission intensity of the fluor... Read More

Plasmonic nanogaps for broadband and large spontaneous emission rate enhancement (2014)
Journal Article
Edwards, A. P., & Adawi, A. M. (2014). Plasmonic nanogaps for broadband and large spontaneous emission rate enhancement. Journal of applied physics, 115(5), 053101. doi:10.1063/1.4864018

We present the optical properties of a plasmonic nanogap formed between a silver metallic nanoparticle and an extended silver film that shows a strong enhancement in the spontaneous emission rate over the whole visible range. In particular, we use th... Read More
