On-Chip Plasmonic Spectrometer
Frontiers in Optics 2016, 2016We report a numerical and experimental study of an on-chip optical spectrometer, utilizing propagating surface plasmon polaritons in the telecom spectral range. The device is based on two holographic gratings, one for coupling, and the other for decoupling free-space radiation with the surface plasmons.

Compact Aberration‐Corrected Spectrometers in the Visible Using Dispersion‐Tailored Metasurfaces
Advanced Optical Materials, 2018The spectral resolution and range of conventional spectrometers are typically limited by optical aberrations of their focusing elements, mainly due to chromatically induced astigmatism and an intrinsically curved focal plane.

The Physics Teacher, 2012
In the fall of 1999 I was shown an Ocean Optics spectrometer-in-the-computer at St. Patricks College at Maynooth, Ireland, and thought that I had seen heaven. Of course, it could not resolve the sodium D-lines (I had done that many years before with a homemade wire diffraction grating1), and I began to realize that inside was some familiar old ...
