Abstract

We report a demonstration of near-field nanoimaging using nanoscale photodetector (NPD) array. The NPD array has detector pixels with subwavelength dimension and is capable of pixel addressing. An active-media finite-difference time-domain simulation of the NPD array shows an imaging resolution of 150 nm for 1.55 μ m light. Additionally, we demonstrate the realization and characterization of the NPD array. The smallest NPD array obtained has 100-nm-wide pixels with 100 nm spacing. A responsivity of 0.28 A W at 1.31 μ m and 3.3 V bias is registered for a 2 × 2 NPD array pixel. The corresponding photocurrent is 735 nA with a dark current of 0.483 nA . Using near-field photocurrent microscopy, an imaging resolution of 390 nm has been demonstrated.
