Abstract:On-chip integration of secondary diffractive optics and bow-tie-shaped InGaAs-based terahertz detectors is presented. Zone plates were produced directly on the bottom surface of a 500 J.lm-thick semi-insulating InP substrate employing direct laser write technique. Integration of the bow-tie detector and the zone plate allows to enhance detection more than one order of magnitude at 0.76 THz. Good correlation between experimental data and 3D finite-difference time-domain simulation results is found. It is confir… Show more
