Attosecond‐Stable Two‐Dimensional Spectroscopy by a Sagnac‐Based Modulating System and a Sub‐4‐fs Continuum Source

Laser &Photonics Reviews, EarlyView.
A novel optical platform integrates a Sagnac‐based interferometer with a high‐brightness multiple‐plate continuum source to advance two‐dimensional electronic spectroscopy. The robust system delivers octave‐spanning, 3.7‐femtosecond pulses and achieves intrinsic attosecond‐level phase stability without active feedback.

Femtosecond‐Laser‐Inscribed Cladding Fiber Bragg Gratings: Architectures, Design Trade‐Offs and Future Sensing Opportunities

Laser &Photonics Reviews, EarlyView.
Femtosecond‐laser inscription enables precise positioning of fiber Bragg gratings within the cladding, introducing new spatial and modal design freedoms. Auxiliary‐waveguide, near‐core evanescent‐field, and direct cladding‐mode‐excitation architectures provide complementary pathways toward multiparameter, vector, distributed, and environmentally ...

Drive‐Efficient GHz‐Rate Binary‐State Updates Enabled by VCSEL Polarization Switching

Laser &Photonics Reviews, EarlyView.
Photonic computing needs a compact node that can hold a binary state and update it fast. A vertical‐cavity surface‐emitting laser biased at its polarization‐switching point could serve as one: its two orthogonal linear polarizations are the two states, and a small electrical drive is enough to move the output from one state to the other at gigahertz ...

Low‐Hysteresis Cellulose‐Based Hydrogels for Strain Detecting

Macromolecular Rapid Communications, EarlyView.
Low‐hysteresis hydrogel with high cellulose content is prepared. The modified cellulose is prepared through a sequential periodate oxidation and borohydride reduction process. The hydrogel can be used as a strain sensor with a gauge factor of 1.1 in the 0%–300% sensing range.

Crystallization in Poly(Ethylene Oxide) Thin Films: Roles of Shear, Confinement, and Homoepitaxy

Macromolecular Rapid Communications, EarlyView.
A comprehensive three‐mechanism framework governing PEO crystallization orientation in thin films was established using GIWAXS and molecular‐level PM‐IRRAS analysis. We demonstrate systematic switching between shear‐induced edge‐on and confinement‐ or homoepitaxy‐induced flat‐on alignment.
