Optical sensor based on Fabry-Perot resonance modes.
An oscillating wave sensor based on Fabry-Perot resonance modes has been developed. Different from the surface plasmon resonance sensors and the waveguide mode sensors in which the sample is located in the evanescent field region, the proposed device contains the sample in the core region that supports the oscillating field. Owing to the strong concentration of the electromagnetic field in the sensing medium, the proposed device exhibits unusual sensitivity enhancement, which has never been exploited in any other devices.
