The growing maturity of nanofabrication has ushered massive sophisticated optical
structures available on a photonic chip. The integration of subwavelength-structured …

Structured light, also known as tailored light, shaped light, sculpted light, or custom light,
refers to a series of special light beams with spatially variant amplitudes and phases …

The capacity of self-healing fields to reconstruct after passing through scattering media may
prove useful in reducing speckle formation. Here, we study the speckle response of the …

In this study, we present a method for free-space beam shaping and steering based on a
silicon optical phased array, which addresses the theoretical limitation of traditional bulk …

A planar nonuniform radially periodic leaky-wave antenna is proposed for the generation of
circular, azimuthally symmetric Airy beams. The design is compact and low cost, and it is …

Until now, many pioneering studies have been conducted on multiwavelength achromatic
lens designs that can eliminate chromatic aberrations at various wavelengths. In these …

With a fixed geometric design, homogeneous change of Indium Selenide (In_2Se_3)
switches the focusing length of a silicon photonic metalens between positive and negative …

Space-time (ST) wave packets are propagation-invariant pulsed optical beams that travel
freely in dielectrics at a tunable group velocity without diffraction or dispersion. Because ST …

Accelerated beams have many applications because of their remarkable ability to propagate
along curved trajectories. An accelerated beam with a non‐monotonic trajectory provides …

On-chip optical interconnection is a promising technology to alleviate the bandwidth
bottleneck in high-performance computing. Compared with wired optical interconnection …
