Wood‐Derived Nanocellulose‐Biocarbon Fresnel‐Zone Plate Lenses for Sub‐THz Frequency Applications

Advanced Materials Technologies, EarlyView.
Wood‐derived nanocellulose and lignin‐based biocarbon were combined to fabricate fully bio‐based Fresnel zone plate (FZP) lenses for sub‐terahertz frequencies. These sustainable FZP lenses exhibit low dielectric loss and high directivity, achieving performance comparable to that of metallic references, and remain functional under environmental stress ...

High‐Stress Si3N4 Reflective Membranes Monolithically Integrated With Cavity Bragg Mirrors

Advanced Optical Materials, EarlyView.
Silicon nitride membranes are record‐breaking mechanical sensors, yet their delicate fabrication and alignment into precision optical cavities have confined them to the laboratory. A monolithic process directly integrates suspended high‐stress Si3N4${\rm Si}_{3}{\rm N}_4$ membranes onto Bragg mirrors, forming self‐aligned optomechanical cavities in ...

Massively Degenerate Coherent Perfect Absorption in Gradient‐Index Fibers

Advanced Optical Materials, EarlyView.
A coherent perfect absorber (CPA) normally operates for only one or very few spatial modes. The CPA proposed here uses a gradient‐index (GRIN) fiber to absorb hundreds of spatial modes at once, its self‐imaging property replacing the bulky free‐space degenerate cavity of earlier designs. An analytic criterion sets how much modal degeneracy is required,
