Thermo‐Optically Tunable Mid‐Infrared Bandpass Filters Comprising Ultra‐Thin Silicon‐on‐Sapphire Metasurfaces

open access: yesLaser &Photonics Reviews, EarlyView.
Ultra‐thin, tunable bandpass filters are a pathway to realizing mid‐infrared spectrometers that are compact, low power, and performant. The authors elicit 141 nanometres of passband tunability in the mid‐infrared in silicon on sapphire zero‐contrast gratings by exploiting silicon's high thermo‐optic coefficient.

Identity‐Enabled CDMA LiDAR for Massively Parallel Ranging with a Single‐Element Receiver

open access: yesLaser &Photonics Reviews, EarlyView.
A novel LiDAR system integrates CDMA modulation with a single‐element detector to achieve massive channel parallel 3D imaging. By using a user identification code and a correlation‐based feedback loop, it overcomes signal collisions and the near‐far problem.

Single‐Pulse Nanomorphology Governs Laser‐Induced Periodic Surface Structure Formation on Metals

open access: yesLaser &Photonics Reviews, EarlyView.
Ultrashort pulse ablation enables generation of self‐organized periodic structures, where evolving nanomorphology controls pulse‐to‐pulse feedback. In noble metals, nanospikes form after the first pulse and localize surface waves, preventing periodic field distributions and thus suppressing their formation.
