Fiber Bragg Gratings with Micro‐Engineered Temperature Coefficients

open access: yesAdvanced Optical Materials, Volume 13, Issue 8, March 13, 2025.
Fiber Bragg gratings (FBGs) are intrinsically responsive to temperature and strain simultaneously. In this research, low‐loss FBGs with micro‐engineered temperature coefficients are fabricated, utilizing refractive index liquid‐filled microchannels in the cladding.

Self‐Assembling Cracks to Fabricate Antireflective Antifogging Metasurfaces

open access: yesAdvanced Optical Materials, EarlyView.
A multifunctional optical device combining antireflective and photothermal antifogging properties is developed by leveraging crack formation in colloidal films. Plasmonic nanoparticle arrays enable localized heating under illumination, while a mesoporous silica coating provides antireflection and water repellency.

Efficient Low‐Voltage Phase Shifter with Inkjet‐Printed Liquid Crystal on a Silicon on Insulator Platform

open access: yesAdvanced Optical Materials, EarlyView.
Demonstration of an electro‐optic phase shifter fabricated by inkjet printing liquid crystal on an integrated silicon photonics chip surface. On a completed silicon photonics wafer (including modulators, detectors, and metallization), the back‐end‐of‐line stack is opened up to inkjet‐print liquid crystal. A phase shift of 6 for 2.7 V is obtained within
