AbstractIn this proposal, AlphaSense, Inc. (AI) and the Oklahoma State University (OKState) detail the development of a novel Cavity Enhanced Terahertz Absorption Spectrometer (CETAS). Key innovations of the proposed system include: a) the use of a small Whispering- Gallery- Mode (WGM) cavity to achieve very long pathlength; and b) the integration of the WGM cavity with the conventional pulsed and continuous wave (cw) THz systems. Consequently, the proposed system will have the following merits: a)Ultra high sensitivity and selectivity, b)Compact, light weight, and relatively low cost, and c)flexible for chemical analysis in different forms.
