Lasing Conditions of Transverse Electromagnetic Modes in Metallic-Coated Micro- and Nanotubes
Nicolás Passarelli, Raúl Bustos-Marún, Ricardo Depine
In this work, we study the lasing conditions of the transverse electric (TE) modes of micro- and nanotubes coated internally with a thin metallic layer. This geometry may tackle so…
