Optics of Nanofibers

Resumé

During the last decade, fabrication and investigation of submicron-sized optical fibers have been received growing attention. Such nanofibers or nanowires can be grown from both inorganic and organic semiconductor materials being arranged in mutually parallel nanoaggregates. Also, selected nanofibers can be placed on a substrate or immersed in a liquid that allows one to study them individually. It has been demonstated that such structures possess promising waveguiding and photoluminescence properties. Under pumping conditions, they operate as a nanolaser. This remarkable progress dictates the necessity of fundamental understanding of underlying optical processes which occur in nanofibers.

In the present talk, we give a brief overview of recent experimental results in this field. Different theoretical models which can be used for the description of waveguiding and light scattering in nanofibers are considered. Emphasis has been put at rigorous approaches which allow analytical analysis. Besides the conventional model of infinitely long cylindrical dielectric waveguide we discuss also diffraction of waveguide modes at the end of a semi-infinite cylinder. The extension of this approach to a cylindrical nanofiber terminated at both ends gives an idea how to determine Fabry-Perot modes of a nanolaser resonator.
