Ultra‐Fast and Energy‐Efficient PZT Optical Tunable Delay Lines for Programmable Photonic Systems

Laser &Photonics Reviews, EarlyView.
Thin‐film PZT enables optical tunable delay lines that simultaneously offer sub‐nanosecond switching, low propagation loss, and zero‐static‐power programmability. A five‐bit on‐chip delay line provides a maximum delay of 387.5 ps with a resolution of 12.5 ps, while reconfigurable MZI splitting ratios further enable non‐volatile optical arbitrary ...

Dual‐Metasurface‐Integrated Fiber Array for Bidirectional Cylindrical‐Vector‐Beam Multiplexed Communication Using Off‐Axis Spatial Manipulation

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 ...
