RESUMEN
Here we fabricated and studied highly-layered Inorganic-Organic Multiple Quantum Well structures and later placed them into metallic low quality factor microcavities. Room-temperature strong exciton-photon coupling is achieved in such single and coupled microcavities. Upon angle tuning, the broad photonic mode of the microcavities is clearly split into two modes at the exciton resonant absorption of hybrid perovskite. The large Rabi splitting upto -213 meV is obtained in good agreement with the theoretical models.
RESUMEN
Optoelectronic-compatible heterostructures are fabricated from layered inorganic-organic multiple quantum wells (IO-MQW) of Cyclohexenyl ethyl ammonium lead iodide, (C(6)H(9)C(2)H(4)NH(3))(2)PbI(4) (CHPI). These hybrids possess strongly-resonant optical features, are thermally stable and compatible with hybrid photonics assembly. Room-temperature strong-coupling is observed when these hybrids are straightforwardly embedded in metal-air (M-A) and metal-metal (M-M) low-Q microcavities, due to the large oscillator strength of these IO-MQWs. The strength of the Rabi splitting is 130 meV for M-A and 160 meV for M-M cavities. These values are significantly higher than for J-aggregates in all-metal microcavities of similar length. These experimental results are in good agreement with transfer matrix simulations based on resonant excitons. Incorporating exciton-switching hybrids allows active control of the strong-coupling parameters by temperature, suggesting new device applications.
