Integrated Microprobes for Terahertz Near-Field Time-Domain Spectroscopy

Despite the large range of promising applications for Terahertz technology, its real deployment has been limited by bulky equipment, mechanical disturbance, high power consumption, and low flexibility systems. Here, we present the design of a THz platform based on photonic integrated devices and photoconductive antennas that can reduce the footprint of all discrete optics in THz spectroscopy systems by two orders of magnitude. The integrated platform aims to contribute to the technological bridge that will take the THz spectrum from bulky systems to on-chip platforms.
