TL;DR: In this paper, two kinds of Fresnel zone plates (FZPs) have been employed as optical coupling devices to enhance the response of versatile laser detection systems, and the simulation and experiment results indicate that the FZPs have selective focusing abilities for wavelength and coherence of the incident lights, which contributes to high collection efficiency to the laser signals and suppression to the ambient lights.

TL;DR: In this paper, a nanofabrication process for the fabrication of SiC nanoimprint templates with ultra sharp tip arrays is described, and the resulting SiC tips are not only of high resolution for nano-imprint lithography, but also of high hardness for high pressure lithography process.

TL;DR: The effects of structural parameters and the shapes of metallic hole arrays on filtering performance are investigated by numerical simulations with the finite-difference time-domain method and then experimentally verified by optical characterizations of fabricated filters using electron beam lithography.

TL;DR: This paper describes in more detail the development of such a beam shaper for hard X-rays at 10 keV with regard to its design, manufacture and optical characterization.

TL;DR: Wang et al. as discussed by the authors developed a reliable approach to control the membrane thickness in the precision of micrometer order by using an optical detection hole with high precision depth, which decides the surface roughness in the Si thinning process.
