Abstract

We demonstrate theoretically and experimentally that one-dimensional plasmons of doped wires are either extended or longitudinally confined when the lateral width of the wires is periodically modulated. Theoretical dispersion curves, calculated within a classical framework, reproduce well the experimental dispersion deduced from Raman scattering on deep etched modulated wires. Zone-edge gap openings, increasing with the modulation amplitude, are exhibited. We show that deep etching allows a good control of complex geometries and provides quasi-abrupt boundary conditions.
