Slab waveguide spatial heterodyne spectrometers for remote sensingfrom space

摘要

We present miniature spectrometers that offer high resolution, increased optical throughput (etendue), and arecompatible with a microsatellite platform. The spectrometers are implemented using arrays of singlemode planar opticalwaveguides and use a Fourier technique for spectra retrieval. We discuss design, fabrication, and first experimentalresults for these multiaperture spectrometers implemented in silicon-on-insulator (S01) waveguides.
