Abruptly autofocusing circular swallowtail beams

Houan Teng et al.

Summary: This study demonstrates a new family of autofocusing beams called circular swallowtail beams (CSBs), based on high-order swallowtail catastrophe, which automatically focus without external components. CSBs have more diversity and tunability compared to previous beams, making them potentially beneficial for flexible optical manipulation. These diverse CSBs could have new applications in optical trapping, medical treatment, or micromachining.

Free-space realization of tunable pin-like optical vortex beams

Domenico Bongiovanni et al.

Summary: This study demonstrates free-space pin-like optical vortex beams with tunable peak intensity and robust antidiffracting propagation. By modulating the amplitude and phase profile of a laser beam, these beams exhibit unique autofocusing dynamics and morph into a high-order Bessel-like profile during propagation. The peak intensity evolution of these beams is controlled by the impressed amplitude structure, representing a novel property with potential applications.

Compact devices for generating multi-focus autofocusing optical beams in free space

Zhibin Liu et al.

Summary: We introduce a new type of optical beam, the multi-focus autofocusing optical beam, which can autofocus multiple times in free space. By designing and overlapping two paraxial accelerating optical beams, we achieve on-axis multi-focus properties, and create compact devices utilizing diffractive optical elements to generate three-focus and four-focus autofocusing optical beams in free space. This work may have potential applications in particle transporting, material processing, and lithography technology.

Multifunctional metasurfaces enabled by simultaneous and independent control of phase and amplitude for orthogonal polarization states

Mingze Liu et al.

Summary: Monochromatic light has three fundamental properties: amplitude, phase, and polarization. A versatile transmission-mode all-dielectric metasurface platform is proposed in this work, capable of independently manipulating the phase and amplitude for two orthogonal states of polarization in the visible frequency range, enabling various light-field manipulation capabilities. This technology opens new possibilities in polarization optics, information encoding, and optical data storage.
