Diffraction grating (DGTD)

Characterize a diffraction grating in response to a broadband planewave at normal incidence. Lumerical provides a set of grating scripts for the DGTD solver, making it easy to calculate common results such as number of grating orders, diffraction angles and grating efficiencies at different wavelengths. Overview Understand the simulation workflow Więcej…

Diffraction grating

This example characterizes a diffraction grating in response to a broadband planewave at normal incidence. Lumerical provides a set of grating scripts as well as “grating order transmission” analysis group, making it easy to calculate common results such as number of grating orders, diffraction angles and grating efficiencies at different Więcej…

Blazed grating

This example shows how to calculate the grating orders from a blaze grating. This grating has many grating orders at each wavelength. In order to capture the signature of the total reflection and transmission, more frequency points in the monitors are required. Simulation setup A blaze grating is shown in Więcej…
