a Schematic diagram of the two-channel WDM. When the Vcombine is applied to the blue and the green Nano-LEDs, two kinds of Mem-EL spikes carrying different information are generated. The two optical signals are multiplexed to form a combined Mem-EL spike. At the receiving end, optical filters with a specific wavelength are used to obtain Mem-EL spikes carrying the original information. b, c Mem-EL spikes generated by Nano-LEDs driven by two Vcombine coded as (b) ‘11001000’ and (c) ‘10101000’, respectively. d Combined Mem-EL spike carrying the hidden information. e, f Mem-EL spikes generated by Nano-LEDs driven by two Vcombine coded as (e) ‘11000110’ and (f) ‘10000110’, respectively. g Combined Mem-EL spike carrying other hidden information.
