Abstract
The development of advanced plasmonic applications is centered on the achievement of active devices. Active plasmonic nanostructures exhibiting tunable resonances have the potential to provide smart materials with a wide range of applications in optoelectronics, including sensing and logic operations. Here, we use finite-difference time-domain simulations to compare the optical properties of nanocones and nanocylinders embedded in two different states of a photochromic medium, first considering a plane wave illumination and then a point dipole one. We show that the photochromic transition induces strong coupling behavior for both illuminations, and it allows a nanocone to effectively enhance one emitter’s emission at one wavelength and quench another emitter at a different wavelength.
