Broadband Measurement and Tuning of the Volatile Thermo‐Optic Properties in Chalcogenide Phase Change Materials

open access: yesAdvanced Optical Materials, EarlyView.
Chalcogenide phase change materials (PCMs) demonstrate a significant switchable volatile thermo‐optic response across visible and telecommunication bands. A broadband measurement is presented showing that some alloys exceed traditional reconfigurable materials in photonic integrated circuit (PIC) applications.

Spatially Deterministic Integration of hBN Single‐Photon Emitters on SiN Waveguides Via Femtosecond Laser Processing

open access: yesAdvanced Optical Materials, EarlyView.
Femtosecond‐laser writing enables spatially deterministic integration of room‐temperature single‐photon emitters in hexagonal boron nitride onto pre‐fabricated silicon nitride waveguides. Confocal photoluminescence microscopy characterizes laser‐written defects, one of which exhibits narrow‐linewidth emission, pronounced polarization dependence, high ...

Oligomerization‐Induced Supramolecular Glass with Superior Processability and Optical Functions

open access: yesAdvanced Optical Materials, EarlyView.
Oligomerization‐induced supramolecular glass (BGG) is formed via a catalyst‐free melt‐quenching strategy from benzoguanamine. The in situ formation of diverse oligomers suppresses crystallization, enabling glass formation. BGG exhibits a high Tg (100.1 °C), polymer‐like modulus, and bright aggregation‐induced emission, and is readily processed into ...

Miniaturized Single‐Photon Level Computational Complex Field Imaging System via Meta‐Optics

open access: yesAdvanced Optical Materials, EarlyView.
8192 Hadamard mask patterns generated by the digital micromirror device (DMD) are projected onto a micro target sample via a metalens. The corresponding modulated intensity spectrum encoded with the spatial information of the target is then captured by a photomultiplier tube (PMT) at the Fourier plane to recover both the amplitude and phase images ...

Submicrosecond Electric Switching of Large Birefringence in the Isotropic Phase of Ferroelectric Nematics

open access: yesAdvanced Optical Materials, EarlyView.
We demonstrate ultra‐fast and efficient electro‐optical switching using the isotropic phase of ferroelectric nematic liquid crystals. A moderate electric field induces a transition to polar ferroelectric nematic order, producing large field‐induced birefringence with sub‐microsecond switch‐on and switch‐off times. This advance enables new opportunities

Modified Chemical Bath Deposition of Tin Oxide for All‐Scalable Perovskite Solar Modules

open access: yesAdvanced Optical Materials, EarlyView.
A stable and scalable chemical bath deposition method for SnOx electron transport layer is developed using PbCl2 to control hydroxide levels. The resulting films enable smooth morphology and excellent optoelectronic properties. Perovskite solar cells fabricated on these T‐SnOx layers achieve 24.5% efficiency and 1000 h operational stability.
