We present spectroscopic experiments and theory of a quantum dot drivenbichromatically by two strong coherent lasers. In particular, we explore theregime where the drive strengths are substantial enough to merit a generalnon-perturbative analysis, resulting in a rich higher-order Floquetdressed-state energy structure. We show high resolution spectroscopymeasurements with a variety of laser detunings performed on a single InGaAsquantum dot, with the resulting features well explained with a time-dependentquantum master equation and Floquet analysis. Notably, driving the quantum dotresonance and one of the subsequent Mollow triplet sidepeaks, we observe thedisappearance and subsequent reappearance of the central transition andtransition resonant with detuned-laser at high detuned-laser pump strengths andadditional higher-order effects, e.g. emission triplets at higher harmonics andsignatures of higher order Floquet states. For a similar excitation conditionbut with an off-resonant primary laser, we observe similar spectral featuresbut with an enhanced inherent spectral asymmetry.
