Functional micro-nano structures for on-chip fourier transform spectrometers

摘要

Spectral analysis can be achieved using various optical microsystems. Amongst, we can cite: Fabry-Pérot and Michelson interferometers, Array Waveguide Grating and Standing wave Fourier Transform spectrometer. Recently, a study aiming miniaturization has been conducted on focal Plane Array Spectrometers (FPAS). Up to the authors' knowledge, this is the first report about a realization of a compact Fourier Transform optical spectrometer based on micro-nano structures, combining a polymer-based integrated optical circuit with movable external mirror for increased sampling and high precision.
