Experimental Verification of the Very Strong Coupling Regime in a GaAs Quantum Well Microcavity

“…[21,25] The slightly smaller of the 1 QW-sample indicates a narrower quantum well [18], in accordance with the slightly larger exciton energy of this sample, cf. Fig.…”

“…(3) with , as fitting parameters. Because of the small Rabi splitting of this sample and since an increase of only a few percent can be expected at 5T [21,25], the contribution The measurement of the diamagnetic shifts for the 28 QW-sample at a detuning of Δ = −10.8meV = −0.62ℏΩ is presented in Figure 3. Fig.…”

“…While we do not have a theory describing the detailed interplay between very strong coupling and the applied magnetic field, we expect the former to be the dominant effect, allowing us to consider a lowest order approximation in B [15,21,25]. In the absence of a magnetic field, …”

Coupling polariton quantum boxes in sub-wavelength grating microcavities

“…Polariton lasing has been demonstrated in a zerodimensional (0D) SWG-DBR hybrid cavity with polarization selectivity. 22,23 Dispersion engineering of the photon and polariton modes has been proposed. 24 Here, we present the study of multiple, coupled SWG cavities.…”

Dispersion Engineering for Vertical Microcavities Using Subwavelength Gratings

“…For example, polarization selectivity and resonance tuning have been demonstrated in vertical cavity surfaceemitting lasers (VCSELs) using SWGs as top-mirrors [16][17][18][19][20]. Recently, strong-coupling and exciton-polariton lasing have been demonstrated in a zero-dimensional SWG-DBR cavity [21,22]. These works on vertical SWGcavities have mainly focused on modes with nearly zero in-plane momentum.…”
