Blazed Metagrating Design

[August 07, 2020]
Following the work of P. Lalanne et al. – pioneers in the field of metasurface research – we construct a blazed metagrating and optimize it in VirtualLab Fusion.
[August 07, 2020]

Following the work of P. Lalanne et al. – pioneers in the field of metasurface research – we construct a blazed metagrating and optimize it in VirtualLab Fusion.

Metagratings and more general metasurfaces are starting to draw ever more attention in different applications. They are known for maintaining a high diffraction efficiency in non-paraxial situations. Polarization-insensitive designs are possible with an appropriate selection of the types of nanopillars as the unit cells for the metagrating. Following the work of P. Lalanne et al. – pioneers in the field of metasurface research – we construct a blazed metagrating and optimize it in VirtualLab Fusion.

Highly Efficient Gratings for Ultrashort Pulses

[July 31, 2020]
We demonstrate, according to T. Clausnitzer et al., how to build up a pulse stretching or compression system with two transmission gratings. Especially, we analyze the polarization dependency of such systems.

Ultrashort pulses prove helpful in many modern applications. To manipulate ultrashort pulses, especially for high-power cases, gratings are often employed to either stretch or compress the pulses. The design of such gratings needs careful consideration: they should maintain high efficiency over a spectrum band, and sometimes even for random polarization. In VirtualLab Fusion, you can design gratings using FMM/RCWA, insert the gratings into a setup with pulsed laser sources for system performance evaluation. We demonstrate with the examples below.

Analyzing Resonant Waveguide Gratings

[July 24, 2020]
We apply the Fourier modal method (FMM / RCWA) within VirtualLab Fusion to analyze resonant waveguide gratings rigorously and demonstrate how to check the resonant effects with focused Gaussian beams.
[July 24, 2020]

We apply the Fourier modal method (FMM / RCWA) within VirtualLab Fusion to analyze resonant waveguide gratings rigorously and demonstrate how to check the resonant effects with focused Gaussian beams.

Resonant waveguide gratings are used for various applications due to their sensitivity to wavelength and polarization. We pick an example from the work of G. Quaranta et al. and analyze its diffraction properties in VirtualLab Fusion. Additionally, we investigate the angular selectivity/sensitivity of the selected resonant waveguide grating, and visualize the diffraction pattern behind it.
