Compact interferometer, related bio-chemical sensor and measurement device

Abstract : The invention relates to a compact and portable interferometer (4) comprising an optical source (40) generating a first beam (B1); an optical chip comprising a first reflective layer (42) and a second reflective layer (45) separated by a dielectric spacer layer (41), the first reflective layer splitting the first beam into a reference beam (BR) and a second beam (B2), the second reflective layer reflecting the second beam into a signal beam (Bs) overlapping the reference beam to create an interference signal (I); a controlled phase modulation means; and a photo-detector (43) receiving the interference signal. The invention also relates to a bio-chemical sensor comprising an interferometer (4) wherein the second reflective layer is an optically-resonant layer chemically functionalized. The invention eventually relates to a measurement device comprising said interferometer or said bio-chemical sensor and a signal analyzing unit processing information from the photo-detector.
