“…Thanks to the rapid development of nanofabrication, the large-scale fabrication of metasurfaces is compatible with the mature CMOS technology. By combining electron beam lithography, DUV projection lithography, and nanoimprinting technologies, 41,42 the mass production costs can be greatly reduced in the future.…”

Optical metasurfaces, which consist of subwavelength scale meta-atoms, represent a novel platform to manipulate the polarization and phase of light. The optical performance of metasurfaces heavily relies on the quality of nanofabrication. Retrieving the Jones matrix of an imperfect metasurface optical element is highly desirable. We show that this can be realized by decomposing the generalized Jones matrix of a meta-atom into two parallel ones, which correspond to the ideal matrix and a phase retardation. To experimentally verify this concept, we designed and fabricated metasurface polarizers, which consist of geometric phase-controlled dielectric meta-atoms. By scanning the polarization states of the incident and transmitted light, we are able to extract the coefficients of the two parallel matrices of a metasurface polarizer. Based on the results of the Jones matrix decomposition, we also demonstrated polarization image encryption and spin-selective optical holography. The proposed Jones matrix retrieval protocol may have important applications in computational imaging, optical computing, optical communications, and so on.

Metalenses and metasurfaces are promising emerging technologies that could improve light collection in light collection detectors, concentrating light on small area photodetectors such as silicon photomultipliers. Here we present a detailed method to characterize metalenses to assess their efficiency at concentrating monochromatic light coming from a wide range of incidence angles, not taking into account their imaging quality.

“…3. This array can then be transformed into multiple rings at the sample surface, by sequentially passing through either a refractive axicon array or an axicon array phase object [14,15], and then through focusing optics. Since all the beams transmitted through the axicon array are all collinear, a single conventional focusing element can be used to form concentric rings at the sample location.…”

Laser-induced strong shock with high efficiency remains a technical challenge, evidenced by the fact that much effort is being invested at the large-scale national laboratories to optimize the laser-induced shock compression of pellets consisting of light elements. However, techniques developed at national laboratories are rarely transferable to university laboratories. Here, we present theoretical work on the design of novel optical cavities intended for strong shock generation at a tabletop scale. The key idea is to utilize multiple laser pulses spatially shaped to form concentric laser rings on condensed matter samples. Each laser ring launches a 2D focusing pressure wave that converges at the common central point. The pulses are delayed in the nanosecond range and spaced by microns, matching the laser scanning speed to the shock speed, which is typically several µm/ns in condensed matter, allowing the pressure waves to superimpose to achieve extremely high pressure. The hereby designed optical cavities are expected to maintain or even exceed the shock excitation efficiency of 10 4 GPa/J reported in our previous work using a single laser ring, where the limiting factor to generate stronger shocks was the saturation of input laser energy. The current design for multiple laser rings bypasses the saturation due to much larger excitation areas, thus the total input laser energy can be dramatically increased. Our work provides a viable pathway toward the application of laser-induced strong shock compression of condensed matters. The current tabletop scheme caters to the need of the shock compression community by providing the flexibility, in contrast to large-scale national labs, to test new shock compression strategies.
