A Clark-Ocone formula in UMD Banach spaces

, 2008
Let H be a separable real Hilbert space and let F = (F_t)_{t\in [0,T]} be the augmented filtration generated by an H-cylindrical Brownian motion W_H on [0,T].

High‐Transmission Mid‐Infrared Bandpass Filters using Hybrid Metal‐Dielectric Metasurfaces for CO2 Sensing

Advanced Optical Materials, Volume 13, Issue 8, March 13, 2025.
This article presents a hybrid metal‐dielectric metasurface in transmission mode for mid‐infrared (MIR) spectroscopy. Composed of germanium on aluminium cylinders atop a calcium fluoride substrate, the metasurface achieves 80% transmission efficiency at λ = 2.6 µm with a narrow full‐width‐half‐maximum of 0.4 µm.

Influence of Outcoupling Layers on Top‐Emitting Perovskite Light‐Emitting Diodes

Advanced Optical Materials, Volume 13, Issue 8, March 13, 2025.
Top‐emitting perovskite LEDs offer benefits over typical bottom‐emitting architectures, toward lasing, improved thermal management, and on‐chip fabrication compatibility. Outcoupling layers offer a strategy uniquely applicable to top‐emitting LEDs to optimize EQE by improving optical outcoupling.

Unveiling Ultrafast Spin‐Valley Dynamics and Phonon‐Mediated Charge Transfer in MoSe2/WSe2 Heterostructures

Advanced Optical Materials, Volume 13, Issue 8, March 13, 2025.
This study reveals the potential to manipulate spin‐valley polarization dynamics in MoSe2/WSe2 heterostructures by quantifying different scattering processes following selective photoexcitation. The results show that these heterostructures enable ultrafast valley‐selective charge transfer, with phonon scattering playing a significant role in the ...

Mode‐dependent Far‐field Radiation of Circularly Polarized Light by a Single Plasmonic Nanohelix

Advanced Optical Materials, Volume 13, Issue 8, March 13, 2025.
The numerical simulations explored the chiroptical response and far‐field radiation behaviors of single plasmonic nanoantennas transitioning into helical structures. This study highlights the ability of these plasmonic nanohelices to regulate the far‐field directionality of radiation power and circular polarization in plasmon‐exciton coupled systems ...

Self‐Assembly of a Tripodal Terpyridine Based Ligand with Luminescent Lanthanide Ions in Solution and Soft Material

Advanced Optical Materials, Volume 13, Issue 8, March 13, 2025.
The tripodal terpyridine‐1,3,5‐benzene tricarboxamide (BTA) ligand 1 is employed in the self‐assembly formation of novel luminescent materials using a range of lanthanide ions. In the polar protic solution, the results from the photophysical measurements are assessed using nonlinear regression analysis, while the functional material properties of the ...

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.
