Photochromic engineering of radiative decay rate in plasmon-emitter coupling

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.& COPY; 2023 Optica Publishing Group

Automated summary

The development of advanced plasmonic applications is focused on achieving active devices. Active plasmonic nanostructures with tunable resonances have the potential to be used in optoelectronics for sensing and logic operations. In this study, we used simulations to compare the optical properties of nanocones and nanocylinders embedded in a photochromic medium. We found that the photochromic transition leads to strong coupling behavior, enabling a nanocone to enhance emission at one wavelength while suppressing emission at another wavelength.
