Ultra Compact and Broadband Fiber Facet Graphene Oxide Microlens Array Fabricated on a Beam‐Expanding Fiber Facet Using Femtosecond Laser Direct Writing Technique

open access: yesNanophotonics, Volume 15, Issue 15, 13 August 2026.
A 400 nm graphene oxide film on a beam‐expanding fiber facet is patterned by femtosecond laser direct writing into a 19‐lens microlens array. The device simultaneously splits a single input beam into multiple 0.67–0.74 NA focus spots with a broadband response from 850 to 1550 nm.

Thermally Modulated Metasurface Sensor for Dynamic and Time‐Resolved Isolation of Extracellular Vesicles

open access: yesAdvanced Materials, Volume 38, Issue 44, 7 August 2026.
A thermally adaptive plasmonic metasurface, functionalized with poly(N‐isopropylacrylamide) (PNIPAM) and anti‐CD63 antibodies, enables precise, on‐demand capture and release of extracellular vesicles (EVs). Delivering high recovery, improved purity, and intact vesicle structure, the platform offers a versatile, label‐free solution for real‐time EV ...

Selective Growth of Bulk‐Like Perovskite in Plasmonic Nanoholes for Enhanced Two‐Photon‐Excited Emission

open access: yesAdvanced Materials, Volume 38, Issue 45, 13 August 2026.
Vacuum‐assisted capillary infiltration delivers perovskite precursors deep into gold nanohole plasmonic hotspots, enabling uniform in situ crystallization of bulk‐like CsPbBr3 within confined cavities. Verified by peel‐off and structural analyses, the hybrid platform shows simulated |E/E₀| ≈2.80 at 800 nm and ∼40‐fold two‐photon absorption‐enhanced ...

Modeling Light‐Induced Synaptic Behavior and Visual Memory of Azopolymeric Compounds

open access: yesAdvanced Optical Materials, Volume 14, Issue 29, 7 August 2026.
In the framework of neuromorphic hardware it is essential to predict the evolution of the internal state of the devices mimicking synaptic functionalities to perform in‐silico modeling of specific computational tasks. Here, we provide a rate‐balance equation model to describe the synaptic‐like response of light‐actuated azopolymeric compounds and ...

Temperature Correction in a Single Luminophore Pressure‐Sensitive Paint Using a Dual‐Emitting Gold Acridine Complex

open access: yesAdvanced Optical Materials, Volume 14, Issue 30, 14 August 2026.
The use of pressure‐sensitive luminescent molecules to quantify surface pressure in wind tunnel testing has revolutionized experimental aerodynamics. This work develops a dual‐emitting gold acridine complex for the simultaneous sensing of pressure and temperature independently of each other.

Impact of Defocusing of the Camera Lens on the Image in Optical Camera Communications

open access: yes, 2018
In this paper, we propose a theoretical model for the intensity of a blurred image of a light source (LS) due to defocusing in optical camera communications. The blurred image is characterized with four parameters of half power full width, maximum intensity, left and right slope of hazy area and we relate them to the LS, channel, and camera settings ...

Full‐Stokes Polarimetry Metasurface‐Enabled Single‐Shot Measurement of the Spin Hall Effect of Light

open access: yesAdvanced Optical Materials, Volume 14, Issue 30, 14 August 2026.
This study presents a metasurface‐enabled approach to measure the spin Hall effect of light in a single‐shot. The metasurface splits a reflected light into six polarization‐dependent focal spots, allowing all Stokes parameters to be obtained from single image.
