Advanced Emissivity Tuning Via Femtosecond Laser Surface Engineering
Femtosecond laser surface processing (FLSP) is employed to fabricate titanium‐based metamaterials with engineered micro/nano‐scale features that exhibit spectrally selective and omnidirectional thermal emissivity. By integrating advanced ellipsometry, electromagnetic modeling, and compositional analysis, the work reveals resonance‐driven emissivity ...

A planar plasmonic metasurface composed of asymmetric gold nanostructures is shown to exhibit both anisotropic and chiral/pseudo‐chiral optical responses. By tailoring the polarization and angle of incidence, the metasurface significantly enhances optical chirality and enables enantiospecific detection.

Micromachined Double‐Membrane Mechanically Tunable Metamaterial for Thermal Infrared Filtering
Herein, a mechanically tunable double‐layer plasmonic metamaterial leveraging the extraordinary optical transmission effect observed in subwavelength arrays of openings within thin metal layers is presented. The concept is experimentally validated by integrating the proposed metamaterial structure into an electrostatic parallel‐plate actuator to create

Generalized Heterodyne Interferometry in Kerr Materials
Interferometry, combined with heterodyne detection, enables simultaneous measurement of light amplitude and phase. This work applies these methods to study nonlinear phase shifts from the optical Kerr effect during laser pulse propagation. Results show the nonlinear index is straightforward to retrieve at low phases, but at higher powers, pulse shape ...

The change in the dielectric function from the heat‐driven amorphous‐to‐crystal Si transformation can be used to engineer large spectral adjustability of Si‐based multilayered narrowband photonic devices operating in the IR region. This effect can be utilized to accurately adjust the resonance wavelength of fabricated amorphous multilayered structures ...
