Terahertz Microscope

Abstract

The primary objective of this project is to develop and demonstrate a suitable THz-wave apparatus as a THz imaging platform with a deep sub-wavelength spatial resolution for Army application; potentially for chemical/biological (CB) detection. The spatial resolution of the new T-ray microscopic imaging platform is orders of magnitude greater than that which is available in a standard free-space T-ray imaging system, with the target of nanometer resolution. This allows us to explore the rich, spectroscopic signatures of hetero-structure, quantum dots, devices and IC circuit diagnostics and molecular vibrations, rotations, and other low-energy transitions for chemical/biological sensing and imaging applications. During the period of this research, the major activities and achievements are in three areas: THz-wave emission microscope, THz near-field microscope using taper waveguide, and THz photonic devices for THz spectroscopy system.
