Towards a sub-10nm optical fibre light source

Brambilla, G. and Renna, F. (2009) Towards a sub-10nm optical fibre light source At 22nd International Microprocesses and Nanotechnology Conference (MNC 2009). 16 - 19 Nov 2009. 2 pp.

Record type: Conference or Workshop Item (Paper)


Light sources with sub-10nm spot sizes have a wealth of applications, including optical memories, optical tweezers, SNOM microscopy and photolithography, just to cite a few. Overall, light confinement is limited by diffraction, which can be seen as a direct consequence of Heisenberg's uncertainty principle [1]. Recent results show that "sub-wavelength" light sources can be manufactured using many techniques, including metamaterials and negative refractive index materials [2,3]. Very often these techniques have been proven inefficient, bulky and do not work at short wavelengths. In this paper, light confinement is attained in nanostructured optical fiber tips exploiting surface plasmon polaritons (SPP).
