Paper Abstract

The goal of this work is to achieve an ultra-miniature spectrometer that has a footprint of less than 1mm x 1mm. The design is based on a novel technique known as Fourier spectral filtering. The sensor consists of a group of photodetectors integrated with different Fourier filters. Each filter, combined with the intrinsic spectral response of the silicon photodetector, was designed to have a unique sinusoidal transmission function. By utilizing multiple sinusoids and collecting the data from all of the detectors, a Fourier transform can be performed and the spectral content of the signal can be extracted.
