Polarization-Sensitive Diffractive Optics and Metasurfaces: "Past is Prologue"
Noah A. Rubin, Yeshaiahu Fainman
Polarization control and switchability are among the most unique features of "metasurfaces" as compared with diffractive optics technologies of the past. Here, we review how the po…

Interferometric modal splitting enables a broadband, dual-polarization on-chip spectrometer
Karl Johnson, Vladimir Fedorov, Dmitrii Belogolovskii +3
The modal dispersion of waveguides often limits integrated photonic devices to operation with a single polarization state. This presents a challenge for sensing and spectroscopy ap…
