Broadband achromatic polarization insensitive metalens over 950 nm bandwidth in the visible and near-infrared

Peng Sun et al.

Summary: Metalenses are important in miniaturized and integrated optical imaging, but designing efficient broadband achromatic metalenses is challenging. This study proposes a phase manipulation approach to design a broadband achromatic metalens with high efficiency. An achromatic polarization-independent metalens is successfully designed for the wavelength range of 450 nm to 1400 nm with over 70% focusing efficiency.

Large-scale achromatic flat lens by light frequency-domain coherence optimization

Xingjian Xiao et al.

Summary: This article presents a new framework for designing multi-level diffractive lenses with achromatic capabilities under non-ideal conditions. Polymer lenses with diameters ranging from 1 to 10 mm were successfully designed and fabricated. Optical characterizations showed that these achromatic lenses have a super broad bandwidth and significant advantages in white-light imaging performance.

Bifacial-metasurface-enabled pancake metalens with polarized space folding

Chen Chen et al.

Summary: This study proposes a pancake metalens that can fold optical path at will using a metacavity, enabling compact imaging systems. The asymmetric and independent functions of the bifacial metasurface are verified, and subsequently, the polarized spacefolding effect of the metacavity is demonstrated. With specifically designed phase, a pancake metalens with on-demand reduction of imaging distance and relatively good imaging performance is achieved.

Broadband metasurface aberration correctors for hybrid meta/refractive MWIR lenses

Ko-Han Shih et al.

Summary: A method for designing multi-metasurface layouts for optical aberration correction is presented. All-dielectric metasurfaces are combined with conventional refractive optics to form a hybrid lens. This approach reduces diffraction loss by optimizing metasurfaces to control optical aberrations.

Chip-scale metalens microscope for wide-field and depth-of-field imaging

Xin Ye et al.

Summary: This study presents a microscopy imaging technology that combines a chip-scale metalens device to achieve simultaneous large field-of-view and depth-of-field. The technology utilizes a SiNx metalens array with a dual-phase design and dispersive spectrum zoom effect. The resulting imaging system achieves a 4-mm x 4-mm field-of-view, 1.74 μm resolution, and 200 μm depth-of-field within a wavelength range of 450 to 510 nm, surpassing the performance of traditional microscopes. Additionally, it is implemented in a miniaturized compact prototype, offering the advantage of portability and convenience.

Bandpass-filter-integrated multiwavelength achromatic metalens

Hanmeng Li et al.

Summary: The design of large-scale, high-numerical-aperture, and broadband achromatism is a challenge in metalens research, but focusing on RGB lights' achromatism can improve efficiency. Implementing a bandpass filter in a metalens results in good RGB achromatism and improved signal-to-noise ratio and resolution in imaging experiments.

Aberration-corrected large-scale hybrid metalenses

Rajath Sawant et al.

Summary: The study focuses on correcting various aberrations in optical systems using hybrid metalenses. Results show that at centimeter-scale hybrid metalenses, chromatic aberration and spherical aberration can be corrected by at least 80% and 70% respectively. The flexibility of adjusting various optical parameters with hybrid metasurfaces opens up new design opportunities for compact and broadband imaging, augmented reality/virtual reality, and holographic projection.

Coherent Raman scattering imaging with a near-infrared achromatic metalens

Peng Lin et al.

Summary: This study introduces a metasurface that converts a low-cost plano-convex lens into a high-quality water-immersion lens, designed to correct chromatic aberrations and improve imaging performance in miniature imaging systems. The hybrid metasurface-refractive lens is utilized for optical differentiation of different polymer microbeads and sample imaging, showing potential for integration into miniature scanning systems for label-free coherent Raman scattering endoscopes.
