Resonances for light matter interaction
State of the art nanophotonics either uses ultra-high
Q microcavities or alternatively broadband plasmonic antennas to achieve
strong coupling between photons and matter for enhanced lighting, lasers,
and strong coupling quantum optics with single emitters. Both approaches face
huge bottlenecks that severely hamper solid state quantum optics: The ultranarrow
bandwidth (1 ppm) of high Q microcavities imposes very slow response times, and
requires intricate stabilization and tuning that is not scalable to many-node
quantum networks. On the other hand, plasmonics is so broadband that it is impractical
for spectral selectivity, and adds huge absorptive losses.
Hybrids of plasmonics and microcavities
We pursue a novel solution to remove these bottlenecks coined “hybrid antenna QED”:
Plasmon antennas placed inside dielectric resonators will allow to reach
very strong light-matter interaction at practical
quality factors (Q ~ 100-1000), thereby creating a platform for
ultrafast nanophotonic integrated quantum optics. Due to the fundamental
physics of how the modes of nanoscale plasmon structures hybridize with
those of dielectric resonators, such as photonic crystal cavities,
this platform will have breakthrough figures of merit for enhanced light
matter interaction, nonlinear optics and strong coupling quantum optics.
By integrating the hybrid antenna QED systems with single emitters
using nanolithography and nanomechanical manipulation techniques, one could ultimately envision
single photon sources, detectors, sensors and nonlinear elements that operate
over THz bandwidth and can be manipulated on ultrafast time scales.
