Abstract

See full text

Presented are systems and methods that perform noninvasive glucose monitoring using mid-infrared self-emission of the human body that acts as a background radiation emitter. Various embodiments accomplish this by taking advantage of the guided-mode resonance (GMR) effect in a number of bandpass filters that are constructed as an array of coplanar filters. The filter array acts as a spectral separator that uses a grating layer and a thin film waveguide to form reflection and transmission filters for particular wavelengths. Unlike, common multi-layer optical filter designs that utilize numerous individual optical filters, a novel GMR filter design comprises an array of filters that may be fabricated from CMOS-compatible materials using only a few thin film and grating layers to filter light. Advantageously, this reduces manufacturing cost and allows for simultaneous monitoring of a number of wavelengths of the glucose spectrum.
