A nanowire-based photonic device and an array employ nanowires connecting between coaxially arranged electrodes in a non-uniform manner along a vertical extent of the electrodes. The apparatus includes reflectors defining a first optical cavity. One or more generated analog signals are converted into one or more digital signals. Thus, axial shifting of the plunger head in the passage hydraulically creates waterwaste pressure andor flow surges in the passage, serving to break up downstream clogs therein.
