18 May 2009 Slab waveguide spatial heterodyne spectrometers for remote sensing from space
Author Affiliations +
We present miniature spectrometers that offer high resolution, increased optical throughput (étendue), and are compatible with a microsatellite platform. The spectrometers are implemented using arrays of singlemode planar optical waveguides and use a Fourier technique for spectra retrieval. We discuss design, fabrication, and first experimental results for these multiaperture spectrometers implemented in silicon-on-insulator (SOI) waveguides.
