With the rapid development of high-speed communication and artificial intelligence
technologies, human perception of real-world scenes is no longer limited to the use of small …

Structured light refers to the arbitrarily tailoring of optical fields in all their degrees of freedom
(DoFs), from spatial to temporal. Although orbital angular momentum (OAM) is perhaps the …

Structured waves are ubiquitous for all areas of wave physics, both classical and quantum,
where the wavefields are inhomogeneous and cannot be approximated by a single plane …

The demand for high-resolution optical systems with a compact form factor, such as
augmented reality displays, sensors, and mobile cameras, requires creating new optical …

The miniaturization of current image sensors is largely limited by the volume of the optical
elements. Using a subwavelength-patterned quasi-periodic structure, also known as a …

Polymer optics have gained increasing importance in recent years. With advancing
requirements for the optical components, the fabrication process remains a challenge. In …

Physical geometry and optical properties of objects are correlated: cylinders focus light to a
line, spheres to a point and arbitrarily shaped objects introduce optical aberrations. Multi …

For more than 150 years, scientists have advanced aberration theory to describe, analyze
and eliminate imperfections that disturb the imaging quality of optical components and …

Freeform optics aims to expand the toolkit of optical elements by allowing for more complex
phase geometries beyond rotational symmetry. Complex, asymmetric curvatures are …

Modern advanced manufacturing and testing technologies allow the application of freeform
optical elements. Compared with traditional spherical surfaces, an optical freeform surface …
