Paper Abstract

A family of methods has been developed recently for generation, control, and visualization of terahertz (THz) phonon-polaritons in polar crystals1. Phonon-Polaritons (below simply "polaritons") are admixture of polar lattice vibration and electromagnetic modes of similar frequency and wave vector. In this paper, we discuss the possible application of phonon-polariton spectroscopic imaging to the chemical sensing. Advantages of the polariton imaging for the use of sensor application include (1) No need for THz optics, (2) Compactness of the cell, and (3) Quick acquisition of time domain signal. In this paper, we present experimental results of solid and liquid samples, and show simultaneous measurement of multiple samples.
