Abstract: In this paper, we report a two-layer five-port diffraction grating by a polarization-independent design under normal incidence. To be different from conventional five-port gratings, ...
Inprentus won a TASA contract to produce diffraction gratings, closely following a recent NASA award, highlighting ...
Abstract: A new method for designing an echelle-type diffraction grating for wavelength division multiplexing (WDM), which is tuned to a single stigmatic point, is introduced. The new grating is ...
