Abstract We demonstrate ultra-thin (1.5-3λ0), fabrication-error tolerant efficient diffractive
terahertz (THz) optical elements designed using a computer-aided optimization-based …

III-V solar cells dominate the high efficiency charts, but with significantly higher cost than
other solar cells. Ultrathin III-V solar cells can exhibit lower production costs and immunity to …

In this paper, a convergence of various approaches within the iterative Fourier transform
algorithm (IFTA) is analysed for the case of phase-only diffractive optical elements with …

This work discusses the design and fabrication of a dual-plane terahertz (THz) hologram
and an extended-depth-of-focus THz diffractive lens. The dual-plane THz hologram consists …

A multi-wavelength expansion of the Gerchberg-Saxton (GS) algorithm is developed to
design and optimize a surface relief Diffractive Optical Element (DOE). The DOE …

摘要研究了一种基于二元位相加密的大信息量数字全息水印方法, 对需隐藏的水印信息用二元
