FIG. 1.

Block diagram of the experimental set-up for the MW modulation experiment. The black arrow points to the central section of the Hall bar where the antidots were patterned. An enlarged view of the patterned antidot lattice is shown in the schematics at the extreme right.

FIG. 2.

Magnetic field dependence of the ratchet photovoltage induced by a 55.4 GHz MW. Ratchet photovoltage for zero attenuation at 0 T is around 0.7 mV. Inset: Zero field ratchet photovoltage and MW power plotted as a function of frequency. The encircled region denotes the range of MW frequency greater than 100 GHz for which maximum photovoltage response is obtained.

FIG. 3.

Digitial oscilloscope recording of the input sine wave (in black) and the signal received from the sample (in red). In the inset, PWM and sine wave retrieved from the sample for two different band pass limits are shown.

FIG. 4.

AM signal carried by MWs of three different frequencies as detected by the ratchet detector.
