Vector beams as the superposition of cylindrical partial waves in bianisotropic media
, 2006 The exact solutions for arbitrary electromagnetic beams in bianisotropic media are constructed. The solutions are expressed using tensor Fourier transform whose physical meaning is the superposition of partial waves.

A Nearly Perfect Implementation of a Broadband Optical Null Media via Space‐Folding
Laser &Photonics Reviews, EarlyView.A space‐folding optical null medium with impedance‐matching layers enables broadband directional wave projection and wavefront engineering. By tailoring the folding ratio and dilution ratio, the structure maintains near‐unity transmittance over 5–9 GHz.

Rotational Anisotropy Raman Spectrometer for High‐Sensitivity Crystallographic Symmetry Analysis
Laser &Photonics Reviews, EarlyView.We introduce rotational‐anisotropy Raman spectroscopy, an enhanced scheme that overcomes the limitations of traditional polarization‐resolved Raman techniques. This method reveals previously inaccessible phonon symmetries and resolves directional anisotropy of phonon‐polaritons in benchmark crystals, establishing a powerful new tool for characterizing ...

Laser &Photonics Reviews, EarlyView.A dual‐layer metasurface is integrated on a fiber‐array facet to realize compact, plug‐and‐play free‐space optical links with cylindrical vector beam (CVB) space‐division multiplexing. An optimized off‐axis collimation layer steers multiple channels, while a Dammann vortex layer performs polarization–topology conversion for bidirectional CVB (de ...

From Planar to 3D Nanophotonic Lenses: Advancing Design, Fabrication, and Applications
Laser &Photonics Reviews, EarlyView.Three‐dimensional nanophotonic lenses are enabled by an integrated workflow that links design parameterization, full‐wave electromagnetic simulation, computational optimization, and freeform fabrication. This Review summarizes how these tools expand optical design freedom beyond a single patterned plane by enriching the local meta‐atom response and ...

Megawatt Cylindrical Vector Beams Generation in a Few-mode Fiber Mamyshev Oscillator
We demonstrate the direct generation of femtosecond cylindrical vector beams from a few-mode Yb-doped fiber Mamyshev oscillator, producing ~260 nJ pulses that are externally compressible to ~65 fs with a peak power of 2.87 MW.
