Monitoring the Etching Process of Hi-Bi Fiber Through a Fiber Loop Mirror
IEEE Photonics Journal, 2017 A method for monitoring the etching process of Hi-Bi fiber is proposed and demonstrated. The birefringence of the etching fiber is accurately calculated by tracking the shift of the interference spectrum in a high-birefringence fiber loop mirror ...

Polarisation-holding in a high-birefringence fibre
Electronics Letters, 1982 The polarisation-holding ability of a 1 km length of high-birefringence fibre is reported. The fibre birefringence increases linearly with frequency and the polarisation-holding parameter h is independent of frequency with a value of 5.5 × 10?6 m?1, indicating average polarisation-holding to ?22 dB.

Advanced Materials, EarlyView.We present SCIENCE, an in‐ear multimodal physiological monitor featuring two key innovations. Water‐triggered morphological expansion (a 2‐mm cylinder to a 9‐mm spindle) achieves conformal adaptation across complex canal geometries. Simultaneously, active biofouling mitigation disrupts cerumen barriers, reducing sensor‐skin impedance by 20%.

All‐Amyloid Functional Coacervates
Advanced Materials, EarlyView.This study introduces an all‐amyloid interfacial complex coacervate technique that employs charge‐mediated or functionalization‐assisted complexation of oppositely charged food protein‐derived amyloid nanofibrils to engineer functional soft constructs across multiple length scales.

Moiré Phase Mapping in Twisted Bilayer Liquid Crystals with Reconfigurable Light Polarization States
Advanced Materials, EarlyView.Twisted bilayer liquid crystals are developed by vertical stacking assembly of two liquid crystals having designer domains and optical properties. These moiré‐symmetry, twisted liquid crystals demonstrate reconfigurable polarization states, moiré patterns and phases controlled by twist angles, providing a route to design active optical devices for ...
