Fig. 6: Working principle of the OECS.

a Schematic illustration of the OECS working principle based on voltage-dependent transmission and computational spectrum reconstruction. b Optical electric field distribution inside the FP cavity. c FP cavity-modulated responsivity, enabling wavelength-selective filtering with complementary spectral bands. d Dark J-V characteristics of the 16-pixel OPD array. e Noise spectrum of the OPD. f D* of OPDs calculated based on the measured noise. g −3 dB cutoff bandwidth and h LDR of OPD. i Normalized responsivity distribution with broadband, voltage-tunable transmittance after EC filter in OECD.
