Phonon-Dressed Mollow Triplets in Semiconductor Cavity-QED
In 1969 Mollow demonstrated that the fluorescence spectrum of a laser driven two-level atom has two Rabi sidebands in addition to a central Rayleigh-scattering peak, producing the so-called “Mollow triplet” . This striking coherent optics phenomenon has been widely studied in a number of atomic and molecular systems. For decades the semiconductor optics community has been trying to access the “quantum-dot Mollow triplet,” and, by combining single quantum dots with semiconductor cavities, recently succeeded .
Quantum dots are often likened to “artificial atoms,’’ but they have unique solid-state microscopic processes, such as electron-phonon scattering. This talk will describe the resonance fluorescence spectra of a driven quantum dot placed inside a high-Q semiconductor microcavity and interacting with an acoustic phonon bath . Several new regimes of phonon-dressed cavity-QED will be discussed—including “excitation induced dephasing” and “cavity feeding”, two pronounced effects that emerge as part of the semiconductor Mollow triplet [3,4]. The underlying physics of electron-phonon scattering with be elucidated through quantum trajectory simulations.
