Paper Abstract

In this paper we propose a novel design of prism-based device as a Fabry-Perot resonance mode sensor. In this setup, liquid or gaseous sample to be probed acts as a core of the F-P device, in which supporting oscillating field, rather than evanescent field. Owing to the strong concentration of the electromagnetic field in the sensing medium, which is about an order of magnitude higher than that in typical evanescent field sensors using SPR, the proposed device exhibits unusual optical properties. It is shown that the fundamental limitation of device sensitivity is set by beam divergence of the laser.
