Enhanced Optical Fiber Lasers and Optical Fiber Sensors Assisted by Micro-drilled Optical Fibers
Optical Fiber Sensors Conference 2020 Special Edition, 2021 Enhanced OFS assisted by micro-drilled optical fibers acting as mirrors are demonstrated. Strain sensitivity improved more than one order of magnitude in comparison with FBG sensors using a 50 μm-waist micro-drilled taper as distributed reflector.

Microbend fiber-optic sensor [PDF]
Applied Optics, 1984 Intensity modulation induced by microbending in multimode fibers is considered as a transduction mechanism for detecting environmental changes such as pressure, temperature, acceleration, and magnetic and electric fields. A generic microbend sensor has been defined and studied, and its components, such as sensing fiber, light source, optical fiber ...

$\mathcal{PT}$ phase control in circular multicore fibers
, 2016 We consider light dynamics in a circular multicore fiber with balanced gain and loss core distribution, and show that transition from unbroken to broken $\mathcal{PT}$ phases can be conveniently controlled by geometric twist of the fiber.

Laser Linewidth Compression in Cascading Brillouin Random Fiber Lasers
IEEE Photonics Journal, 2022 Cascaded Brillouin random fiber lasers (BRFLs) with laser linewidth compression were theoretically and experimentally demonstrated. Thanks to photon-phonon coupled interplay as well as randomly distributed feedback along silica fibers, the coherent time ...

Strength through diversity: how cancers thrive when clones cooperate
Molecular Oncology, EarlyView.Intratumor heterogeneity can offer direct benefits to the tumor through cooperation between different clones. In this review, Kuiken et al. discuss existing evidence for clonal cooperativity to identify overarching principles, and highlight how novel technological developments could address remaining open questions.

Invited - Sensing applications based on all-optical excitation and interrogation of forward stimulated Brillouin scattering [PDF]
EPJ Web of ConferencesBoth backwards and forward Brillouin scattering are powerful tools for sensing applications. While most of the approaches lead to distributed fiber sensors applications, we present a number of all-optical techniques that allow fabricating point-to-point ...
