Fhod3 in zebrafish supports myofibril stability during growth of embryonic skeletal muscle
Developmental Dynamics, EarlyView.Abstract Background Actin filament organization in cardiomyocytes critically depends on the formin Fhod3, but a role for Fhod3 in skeletal muscle development has not yet been described. Results We demonstrate here that in zebrafish mutated for one of two fhod3 paralog genes, fhod3a, skeletal muscle of the trunk appears normal through 2 days post ...

A Fully‐Connected Chip‐Integrated Reconfigurable Mode‐Pairing Quantum Key Distribution Network
Laser &Photonics Reviews, EarlyView.This work constructs a fully connected reconfigurable chip‐integrated quantum key distribution network via the mode‐pairing protocol. Hybrid ECL and WSS chips cut wavelength and port overhead, realizing arbitrary‐user key sharing with merely two wavelengths.

Nonlinear properties of optical microfibres
, 2013 Glass microfibre waveguides offer an intriguing platform for the investigation of nonlinear effects, due to their high effective nonlinearity which arises from the tight modal confinement down to dimensions comparable to the wavelength of guided light ...

Rotational Anisotropy Raman Spectrometer for High‐Sensitivity Crystallographic Symmetry Analysis
Laser &Photonics Reviews, EarlyView.We introduce rotational‐anisotropy Raman spectroscopy, an enhanced scheme that overcomes the limitations of traditional polarization‐resolved Raman techniques. This method reveals previously inaccessible phonon symmetries and resolves directional anisotropy of phonon‐polaritons in benchmark crystals, establishing a powerful new tool for characterizing ...

Optics Express, 2005 We examine the transmission characteristics of a NOLM device using a symmetrical coupler, highly twisted fiber, and a quarter-wave (QW) retarder plate introducing a polarization asymmetry in the loop. We demonstrate high dynamic range with controllable transmissivity, and good stability over long times. We experimentally study the transmission behavior

From Planar to 3D Nanophotonic Lenses: Advancing Design, Fabrication, and Applications
Laser &Photonics Reviews, EarlyView.Three‐dimensional nanophotonic lenses are enabled by an integrated workflow that links design parameterization, full‐wave electromagnetic simulation, computational optimization, and freeform fabrication. This Review summarizes how these tools expand optical design freedom beyond a single patterned plane by enriching the local meta‐atom response and ...

Tunable Optical Filters Using Compound Ring Resonators for DWDM [PDF]
, 2003 The device is based on a loop mirror in a ring resonator. The loop mirror allows tuning by changing the coupling coefficient of a directional coupler. The loop mirror is implemented using a Sagnac configuration to have the same optical path between the ...

High resolution polarization-independent high-birefringence fiber loop mirror sensor
Optics Express, 2015 In this work, two all polarization-maintaining (PM) high-birefringence (Hi-Bi) fiber loop mirrors (FLM) which are immune to external polarization perturbations are validated both theoretically and experimentally. Simplified and stable versions of classical FLMs were attained using a PM-coupler and by fusing the different Hi-Bi fiber sections with an ...
