Data from: Ultracompact on-chip spectral shaping using pixelated nano-opto-electro-mechanical gratings

The ability to shape light spectra dynamically and arbitrarily would
revolutionize many photonic systems by offering unparalleled spectral
efficiency and network flexibility. However, most existing optical
components have rigid spectral functionalities with limited tunability,
hindering compact and fast optical spectral shaping. We introduce a
pixelated nano-opto-electro-mechanical (NOEM) grating that exploits
electromechanically induced symmetry breaking for precise, pixel-level
control of grating coupling strength, yielding a miniaturized (~0.007 mm²)
on-chip spectral shaper. We demonstrate the synthesis of grating pixels
for arbitrary spectral responses and achieve rapid (<10 ns),
high-contrast (>100 dB) wavelength-selective switching via
collective, nanometer-scale electrostatic perturbations. Our pixelated
NOEM grating delivers exceptional spectral manipulation capabilities in an
ultracompact, on-chip manner, offering prospects for next-generation
optical information networks, computing architectures, and beyond.
