Abstract :
Planar resonator arrays are becoming increasingly important for THz sensing applications. Minute amounts of sample substances placed at the array surface can be detected with orders of magnitude enhanced sensitivity compared to pure transmission because of resonator-induced local field enhancement. However, for further optimization of sensitivity and read-out speeds as well as advanced scientific investigations of sub-wavelength-scale EM properties, a non-invasive method for high-resolution field sampling is required. In this work, we demonstrate photoconductive microprobes for the high-resolution and high-speed near-field read-out of resonator arrays at acquisition speeds of up to 3 ms/resonator.
