Fig. 1: Large area, high-speed, electro-optic spatial light modulator for massively parallel imaging or remote sensing.

A beam of light E_inc is incident onto an array of n × n electro-optic modulators that are controlled by a set of driving voltages V_n at radio-frequencies \({f}_{{{{{{{{\rm{mod}}}}}}}},{{{{{{{\rm{n}}}}}}}}}\). The modulators are resonant by design and covered by a single layer of electro-optic molecules (see inset transmission function). Consequently, their resonant wavelength can be shifted by the external driving voltages through the electro-optic (Pockels) effect that changes the refractive index of the modulators by Δn ~ V_n. When the incident beam oscillates at a given operation (OP) wavelength λ_op, the transmission is modulated by the voltage (see correspondence between V, Δn, and T). In an imaging experiment, the spatial and temporal control over the incident light achieves gray-scale QR codes in its far-field. In a remote sensing experiment, the ability to modulate each pixel with an unique frequency \({f}_{{{{{{{{\rm{mod}}}}}}}},{{{{{{{\rm{n}}}}}}}}}\) allows to link the RF domain with well-defined space bins. As a result, while performing a single-pixel detection of all channels at one single high-speed photodiode, a multipixel map of the environment is reconstructed by tracking, in parallel, the amplitudes of the individual transmitted modulation frequencies and their evolution over time.
