Travelling-Wave Modeling of Dynamics of Ultrafast Reflective-Intracavity-Filter Tunable Fabry-Pérot Lasers for Optical Coherent Tomography [PDF]

open access: yes, 2011
The dynamics of Fabry-Pérot external-cavity laser diodes frequency-swept at a high rate using a tunable intracavity filter are investigated by travelling-wave modelling. The effect of broad and narrow bandwidth filter properties and linewidth enhancement

Extreme‐Thickness Meta‐Membrane for Controlling Terahertz Vectorial Beams

open access: yesAdvanced Science, EarlyView.
We propose ultra‐thin (λ/30) transmissive terahertz metasurfaces combining near‐field resonant and detour phases in coupled‐slit meta‐atoms, enabling continuous phase and polarization control beyond conventional designs. Based on leaky‐mode theory, scalar and vectorial terahertz Bessel beams at 0.39 THz are experimentally demonstrated, with ...

Stress Accumulation Induced by Ion Exchange for Synchronous Modulation of Mode and Wavelength in Microlasers

open access: yesAdvanced Science, EarlyView.
This work demonstrates a paradigm‐shifting strategy to simultaneously achieve broadband wavelength tunability and single‐mode control within a single perovskite microwire structure. Using a facile heating‐assisted solid–solid anion‐exchange strategy, we synthesized phase‐pure CsPbClxBr3‐x microwires that exhibit the widest reported continuous lasing ...

Quantum statistics of light transmitted through an intracavity Rydberg medium

open access: yesNew Journal of Physics, 2014
We theoretically investigate the quantum statistical properties of light transmitted through an atomic medium with strong optical nonlinearity induced by Rydberg–Rydberg van der Waals interactions.

A Review of Failure Modes and Safety Strategies of Lithium‐Ion Batteries from Materials to Systems

open access: yesAdvanced Science, EarlyView.
A cascade‐aware framework is presented for lithium‐ion battery safety, linking thermal runaway initiation, acceleration, runaway reaction, and propagation with material‐, cell/pack‐, and system‐level interventions. By integrating failure mechanisms, quantitative safety indicators, and staged interception strategies, this review highlights how safer ...

Patient-reported experience with Fabry disease and its management in the real-world setting: results from a double-blind, cross-sectional survey of 280 respondents

open access: yesOrphanet Journal of Rare Diseases
Background Fabry disease (FD) is a rare X-linked lysosomal storage disorder with a heterogeneous clinical presentation. Patients with FD may exhibit early signs/symptoms including neuropathic pain, gastrointestinal complaints, and dermatologic ...

Ultracold atoms in disordered potentials: elastic scattering time in the strong scattering regime

open access: yesNew Journal of Physics, 2019
We study the elastic scattering time ${\tau }_{{\rm{s}}}$ of ultracold atoms propagating in optical disordered potentials in the strong scattering regime, going beyond the recent work of Richard et al (2019 Phys. Rev. Lett. 122 100403).

An investigation of chirped fibre Bragg gratings Fabry-Perot interferometer for sensing applications [PDF]

open access: yes, 2005
Fibre interferometer configurations such as the Michelson and Fabry-Perot (FP) have been formed using uniformed and chirped Fibre Bragg Gratings (FBG) acting as partial reflectors. As well as increasing the dynamic range of the interferometer, chirped

Tunable transform-limited pulse generation using self-injection locking of an FP laser [PDF]

open access: yes, 1993
Wavelength-tunable, near transform-limited pulses have been generated using a Fabry-Perot laser diode coupled to a fiber loop containing a fiber Fabry-Perot resonator (FFPR) and a polarization controller.
