Paper Abstract

We have demonstrated a novel bio-signal processing technique with hybrid bio-systems using an optical microcavity ring resonator. The intensity of the transmitted light through the ring resonator has a periodic and sensitive region depending on the wavelength of the incident light into the ring resonator. It is possible to detect biomolecules with the ring resonator, because the resonance profile is shifted by refractive index changes due to an amount of biomolecules on the surface of sensing areas. Our processing technique is based on using dual-wavelength. In this scheme, high accuracy can be achieved by comparing the intensity of two incident lights which has channel spacing of the half period of the sensitive region. More detailed experimental results on a novel bio-signal processing technique will be presented.
