Abstract:
1. A micro-resonator sensor using an evanescent wave of a total reflection mirror, the sensor comprising: an input waveguide guiding inspection light incidented on one end section thereof to the other section; a total reflection mirror disposed at the other section of the input waveguide such that an incident angle made with the input waveguide is larger than a total reflection threshold angle at which the inspection light is totally reflected, and comprising a receptor provided on the other side from the side on which the inspection light is incidented and combined with a measurement-subject material; and an output waveguide disposed at a certain output angle relative to the total reflection mirror and outputting a reflection light whose intensity changes according to the measurement-subject material due to an interaction between the evanescent wave generated by the inspection light incidented to the total reflection mirror and the measurement-subject material.
