TL;DR: In this article, a novel concept of designing silicon photonics metamaterials for perfect near-infrared light absorption is proposed, which shows combined vortex and crossed-junction two-dimensional waveguide-like flows as outcomes of optical field singularities.

TL;DR: In this article, a new dielectric Fabry-Perot cavity was designed for a resonant enhancing optical absorption by a thin absorber layer embedded into the cavity, which was shown to meet the combined challenges of increasing the absorbing efficiency of the entire device up to ~ 100 % and reducing its size and overall complexity.

TL;DR: In this paper, the front (furthest from the illuminated side) mirror is a grating structure with nearly perfect retroreflection, and the results indicate that this new type of cavity meets the combined challenges of significantly increasing the absorption efficiency and reducing the overall complexity and size of the entire device, in comparison to a conventional resonant cavity, in which both mirrors are formed from quarterwavelength multilayer stacks.

TL;DR: In this article, the printing of polydimethylsiloxane (PDMS) lines and the control of their physical dimensions are investigated; the applied parameters are different humidity levels, n-hexane dilution proportions and different tip velocities.

TL;DR: In this article, a new dielectric Fabry-Perot cavity was designed for a resonant enhancing optical absorption by a thin absorber layer embedded into the cavity, which was shown to meet the combined challenges of increasing the absorbing efficiency of the entire device up to $\sim 100$% and reducing its size and overall complexity, while maintaining a fairly good tolerance against the grating's fabrication errors.
