Biosensor for glucose detection

Abstract

The present disclosure provides a biosensor for glucose detection including a meta-lens, a first grating coupler below the meta-lens, a first demultiplexer, and a plurality of first photodiodes below or levelled with the first demultiplexer. The meta-lens refracts an incident light into a first light beam and a second light beam spatially spaced apart from the first light beam, where a first wavelength range of the first light beam is non-overlapped with a second wavelength range of the second light beam. The first light beam is directed by the first grating coupler and demultiplexed into a plurality of first sub-light beams by the first demultiplexer. Each of the first sub-light beams has a peak wavelength, and each of the peak wavelengths is different from any of the other peak wavelengths. Each of the first sub-light beams is corresponding to each of the first photodiodes, respectively.
