Very strong coupling in GaAs-based optical microcavities
Very strong coupling in GaAs-based optical microcavities
We show that when following a simple cavity design metric, a quantum well exciton-microcavity photon coupling constant can be made substantially larger than the exciton binding energy in GaAs-based optical microcavities. Consequently the very strong coupling regime becomes accessible in which a strong asymmetry between upper and lower polariton branches …
