Spatial Heterodyne Fourier-Transform Waveguide Spectrometers

Overcoming current resolution limits of optical spectroscopy could revolutionize research in diverse fields such as atomic and molecular spectroscopy, bio-chemistry, and astronomy. In this chapter, we explore the opportunities opened by spatial heterodyne Fourier-transform spectroscopy, presenting both its early bulk-optics implementations and its latest applications in waveguide optics and silicon photonics. Spatial heterodyne …
