Large photonic strength of highly tunable resonant nanowire materials
| Abstract | We demonstrate that highly tunable nanowire arrays with optimizeddiameters, volume fractions, and alignment form one of the strongestoptical scattering materials to date. Using a new broad-band technique,we explore the scattering strength of the nanowires by varyingsystematically their diameter and alignment on the substrate. Weidentify strong Mie-type internal resonances of the nanowires which canbe tuned over the entire visible spectrum. The tunability of nanowirematerials opens up exciting new prospects for fundamental and appliedresearch ranging from random lasers to solar cells, exploiting theextreme scattering strength, internal resonances, and preferentialalignment of the nanowires. Although we have focused our investigationon gallium phosphide nanowires, the results can be universally appliedto other types of group III-V, II-VI, or IV nanowires. |
