Surface Enhanced Spectroscopy
Surface enhanced spectroscopy has the potential to enhance both the in and outcoupling of photons with a molecule by many orders of magnitude. However, conventional plasmonic surface enhancement employs only single-resonant enhancement, providing optimal enhancement of at most a single optical transition (i.e. the in or outcoupling). So-called dual-resonant enhancement can be used to overcome this issue, but requires more complex surface designs.
In a recently established research line at OMEL, we are developing multiresonant plasmonic platforms for surface enhanced spectroscopy. Building on the group’s expertise in the fabrication of high quality plasmonic substrates, we will develop versatile plasmonic platforms in which widely tunable multiple resonances will allow for simultaneous optimization of excitation, emission and scattering transitions in molecular systems.
