Abstract
Disclosed herein is a system for detecting the presence of an chemical in a sample comprising a laser light source for generating a beam of light; a beam splitter that is operative to split the beam of light into a first beam of light and a second beam of light; a reference cell and a first recording device that are operative to receive the first beam of light; where the first recording device is downstream of the reference cell; a resonator that is operative to receive the second beam of light via a coupler; where the resonator contains the sample that contains the chemical; a phase modulator and a second recording device that lie downstream of the resonator and are operative to receive the second beam of light.
