Versatile Control of Spectral Emissivity in Mid‐Infrared Metasurfaces via Silicon Microstructuring
Advanced Optical Materials, Volume 14, Issue 10, 13 March 2026.A family of metasurfaces is obtained very simply, solely through the structuration of a single‐crystal silicon surface, without any other material involved. Based on the infrared plasmonic behavior of highly doped silicon, further control of surface topography by micro‐ and nano‐structuration is found to enable an avenue of options toward tailoring its

Reinforcement Learning Enabled Nanophotonic Devices
Laser &Photonics Reviews, Volume 20, Issue 6, 18 March 2026.A reinforcement learning algorithm is used to design photonic devices. The method creates metagratings and grating couplers that efficiently control both the direction and polarization of light. Further, a reinforcement learning approach is used to design in‐plane integrated photonic devices. This approach paves the way for advanced photonic components

Polarization-Independent Filter Based on 2-D Crossed Grating Under Oblique Incidence
IEEE Photonics Journal, 2018 The existing polarization-insensitive filters based on two dimensional (2-D) grating are mostly under normal incidence. However, in filtering optical devices, the normal incidence regime is usually avoided because it requires the use of beam separators ...

Physical properties of the tunic in the pinkish-brown salp Pegea confoederata (Tunicata: Thaliacea)
Zoological Letters, 2018 Background Invisibility in the water column is a crucial strategy for gelatinous zooplanktons in avoiding detection by visual predators, especially for animals distributed in the euphotic zone during the daytime; i.e., surface dwellers that do not ...

Mitigating the Impact of Asymmetric Deformation on Advanced Metrology for Photolithography
Applied SciencesControlling overlay in lithography is crucial for improving the yield of integrated circuit manufacturing. The process disturbances can cause undesirable morphology changes of overlay targets (such as asymmetric grating), which can significantly impact ...
