Enhanced Cavity Optomechanics with Quantum-Well Exciton Polaritons

Ag/Au alloy entangled in a protein matrix: A plasmonic substrate coupling surface plasmons and molecular chirality

“…Numerous sensing devices based on the coupling of the optical and mechanical domains [1][2][3][4] [5,6] in the form of optomechanical resonators (such as cantilevers [7] and cavities [8] ) have been developed during the past decade [1] as a result of recent micro and nanooptics advances. The optomechanical coupling is classified as dispersive and dissipative [9] , depending on whether the mechanical resonator modulates the resonant frequency by changing the cavity length or the decay rates by altering the optical input coupling or intracavity loss and these variations measure the system sensitivity.…”

From cavity optomechanics to cavity-less exciton optomechanics: a review

“…128 N. Carlon Zambon et al theoretically investigated the case where the microcavity exciton optomechanical system operates in the strong exciton–photon coupling regime. 131 The optical and excitonic resonances are parametrically modulated by the interaction with a mechanical mode and polariton–phonon interactions would enhance optomechanical coupling by two orders of magnitude. Besides, they analyzed that polariton nonlinearities affect dynamical back-action, modifying the capability to cool or amplify the mechanical motion.…”

Coherent anharmonicity transfer from matter to light in the THz regime

“…Cavity QED observables such as the vacuum Rabi splitting have also been demonstrated with material dipoles in infrared (THz) resonators at room temperature using intersubband transitions [14][15][16][17] and molecular vibrations [18][19][20][21][22][23], for applications such as infrared photodetection [24] and controlled chemistry [25,26]. The enhancement of the spontaneous emission rate of material dipoles in a weakly coupled cavity via the Purcell effect [27][28][29] has been used over different frequency regimes for reservoir engineering [30,31], dipole cooling [32,33] and quantum state preparation [34]. In infrared cavities, the Purcell effect can be an effective tool for studying the relaxation dynamics of THz transitions in materials [35][36][37], given the negligible radioactive decay rates at these frequencies in comparison with non-radioactive relaxation processes [38,39].…”
