A novel high-speed near-field imager is presented based on channelized nanoscale-pixel photodetector (NPD) array with metal-semiconductor-metal detector structure and graded In0.53Ga0.47As/In0.52Al0.48A s superlattice as active medium. The NPD array can reach sub-wavelength spatial resolution of <λ/8.
