In this tutorial, we will demonstrate in detail how what we learned in the previous tutorials can be used to optimize a grating coupler in two dimensions. This structure consists of a waveguide with ...

Q: What are diffraction gratings? A diffraction grating is an optical component for spectroscopy that splits light into different wavelengths. A typical diffraction grating has thousands of ...

Abstract: We propose and validate a new approach for low-back-reflection and high-efficiency silicon waveguide grating couplers (GC) with a fully etched structure. Enhanced coupling efficiency is ...

While Ekeler will still be on the injured reserve, fantasy managers should not trust McNichols as a viable option, as he could very well cede No.2 duties to Rodriguez for the second straight week.

Washington Commanders running back Jeremy McNichols should not be started in any format this weekend when he faces the Atlanta Falcons. Even with Austin Ekeler (concussion) sidelined, McNichols ...
