Room temperature strong coupling from CdSeS/Zn quantum-dots embedded into a tunable porous-silicon Fibonacci-conjugated array could be observed when exciton's energy was tuned either to the photonic-edge or the defect in the middle of the…
Strong coupling in the conventional sense requires that the Rabi cycling process between two interacting states is faster than other dissipation rates. Some recent experimental findings show intriguing properties that were attributed to…
