Scientific Achievement

We present experimental evidence that the Rabi splitting observed in metamaterials-semiconductor strongly-coupled systems is directly proportional to the capacitance of the resonator

Significance and Impact

Now we know how to maximize light matter interaction between metallic nanocavities and dipoles/emitters. This could enable polariton lasing & luminescence and new types of detectors or sensors.

Research Details

–Fabricated metamaterial arrays on top a two-level using an intersubband transition in a semiconductor heterostructure.

–measured Rabi-splitting from transmission curves for different resonator geometries.

–correlated measurements with equivalent electrical circuit model (published recently by us) to describe the light−matter interaction in these systems.
