Multidimensional coherent spectroscopy directly unravels multiply excited states that overlap in a linear spectrum. We report multidimensional coherent optical photocurrent spectroscopy in a semiconductor polariton diode and explore the excitation ladder of cavity polaritons. We measure doubly and triply avoided crossings for pairs and triplets of exciton polaritons, demonstrating the strong coupling between light and dressed doublet and triplet semiconductor excitations. These results…

Photon-photon polaritons in χ(2) microresonators

We consider a high-Q microresonator with χ nonlinearity under conditions when the coupling rates between the sidebands around the pump and second harmonic exceed the damping rates, implying the

Enhanced Interactions between Dipolar Polaritons.

A substantial increase in interaction strength between dipolar polaritons is reported as the size of the dipole is increased by tuning the applied gate voltage, indicating that dipolar Polaritons could constitute an important step towards a demonstration of the polariton blockade effect, and thereby to form the building blocks of many-body states of light.

A system of optically guided, electrically polarized exciton-polaritons (“dipolaritons”) that displays up to 200-fold enhancement of the polariton- polariton interaction strength compared to unpolarized polaritons is demonstrated.

Two-quantum many-body coherences in two-dimensional fourier-transform spectra of exciton resonances in semiconductor quantum wells.

By measuring the real part of the signals, it is determined that the spectra are dominated by two-quantum coherences due to mean-field many-body interactions, rather than bound biexcitons.
