Early Distraction in Neonates With a Bioresorbable Plate for Bilateral Vocal Fold Immobility

The Laryngoscope, EarlyView.
We describe a novel surgical technique in two neonates with idiopathic bilateral vocal fold immobility (BVFI) using early posterior cricoid distraction with placement of a poly‐l‐lactic acid (PLLA) bioresorbable plate to improve the glottic aperture. Both patients experienced complete resolution of stridor and achieved full oral feeding within 2 weeks,

A Fully‐Connected Chip‐Integrated Reconfigurable Mode‐Pairing Quantum Key Distribution Network

Laser &Photonics Reviews, EarlyView.
This work constructs a fully connected reconfigurable chip‐integrated quantum key distribution network via the mode‐pairing protocol. Hybrid ECL and WSS chips cut wavelength and port overhead, realizing arbitrary‐user key sharing with merely two wavelengths.

Transcending the Space‐Bandwidth and Lighting Trade‐Offs: A Programmable Self‐Mixing Interferometry Imager for Cross‐Scale Surface Inspection

Laser &Photonics Reviews, EarlyView.
This work reports a laser diode‐based self‐mixing interferometry imager featuring illumination‐invariance imaging, a 500 kHz pixel rate, and an 8.77 µm lateral resolution. It also features a programmable field‐of‐view and leading space‐bandwidth product that surpasses existing technologies by an order of magnitude, enabling cross‐scale workflow ...

Single‐Lens Counter‐Focused Ultrashort Laser Pulses for Enhanced Microplasma Formation Inside Silicon

Laser &Photonics Reviews, EarlyView.
A polarization‐dependent liquid–crystal spatial light modulator is used to generate coaxial double‐focus laser beams with independently tunable focal separation and intensity. Applied to silicon, this configuration enables counterpropagating pulse interactions using a single focusing element, enhancing nonlinear excitation and achieving near‐critical ...
