DOI: 10.1016/j.optcom.2018.04.078
Abstract: Abstract In a previous paper [Opt. Commun. 407 (2018) 217–226], there was proposed a light-efficient, high-numerical-aperture focusing system which is based on a monolithic assembly of an axicon and an inclined parabolic annular reflector (AXIPAR)… read more here.

DOI: 10.1038/s41467-024-55095-z
Abstract: Sampling is a pivotal element in the design of metasurfaces, enabling a broad spectrum of applications. Despite its flexibility, sampling can result in reduced efficiency and unintended diffractions, which are more pronounced at high numerical… read more here.

DOI: 10.1364/ao.465761
Abstract: In Fizeau interferometry for high-numerical-aperture spherical surface tests, the mechanical phase shift becomes spatially nonuniform within the observation aperture. We divided the aperture into annular regions and calculated the object phase using several algorithms designed… read more here.
