The file "Transmittance_circular.oggu" contains the magnetic field dependencies of the transmittance as a function of the magnetic field, normalized to its maximum value Tmax (b), for two circular polarisations of incident light.
The file "Resistivity_ratio.oggu" contains the resistivity ratios at the extrema of the MIRO signals, illustrating the asymmetry of MIRO between the CR-active and CR-passive polarities for η = 1 and η = −1 . The solid curve shows the ratio of the Drude absorption calculated for η = 1 using parameters extracted from the dark transport measurements.
The file "Decomposition_circular.oggu" shows the circular decomposition of the electric field in the waveguide: the incident E+ and distorted E− helicity components of the near field reaching the 2DES. Also shown is the size dependence of the MIRO asymmetry in experiments with varying diameters of the diaphragm. Curves are calculated using Eqs. (1), (3), and (5) of the main manuscript.
Abstract (English)
We demonstrate that the long-debated immunity of the microwave-induced resistance oscillations (MIRO) to the sense of circular polarization is in fact not an inherent property of this phenomenon in solid-state two-dimensional electron systems (2DES): We detect an up to 30 times larger MIRO signal for the cyclotron resonance (CR) active helicity, fully consistent with the concurrently measured transmission and the deduced
CR shape of the Drude absorption. Using a 2DES as a sensitive sensor of the actual polarization state, we further study extrinsic near-field effects capable of producing an apparent immunity of the photoresponse.
