Fiber Bragg Gratings with Micro‐Engineered Temperature Coefficients

Advanced 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.

Giant Rabi Splitting and Polariton Photoluminescence in an all Solution‐Deposited Dielectric Microcavity

Advanced Optical Materials, EarlyView.
Lowering the barrier for researchers to explore polariton physics: A fully solution‐processed dielectric polariton microcavity incorporating Rhodamine 6G with tunable Rabi splitting up to 400 meV and photoluminescence. Abstract Planar microcavity polaritons have recently emerged as a promising technology for improving several performance ...

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

Advanced 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

Suppressed Stokes Shifts and Hot Luminescence from Quantum Dots within Plasmonic Nanocavities

Advanced Optical Materials, EarlyView.
This study demonstrates the suppression of the Stokes shift in lead sulfide quantum dots through integration with plasmonic nanocavities. By enhancing spontaneous emission and altering exciton relaxation pathways, this approach enables direct band‐edge emission with improved radiative efficiency, highlighting the powerful role of nanophotonic ...
