New analytical tools are needed to identify chemical degradation and failure mechanisms in Li-ion batteries. Here, the authors report an operando Raman spectroscopy method, based on hollow-core optical fibres, that enables monitoring the chemistry of

Fiber optic implantation in deep areas of the rodent’s brain for MRI combined with optogenetics is challenging. Here the authors use an MRI-guided robotic arm as the navigation method for accurate fiber optic placement and precise microinjection du

We report on the properties of tapered single-ring hollow-core photonic-crystal fibers, with a particular emphasis on applications in nonlinear optics. The simplicity of these structures allows the use of non-invasive side-illumination to assess the

We report on intra- and inter-modal four-wave-mixing (FWM) in N-fold rotationally symmetric (C_N) single- and multi-core chiral photonic crystal fiber (PCF), created by spinning the preform during fiber drawing. The non-circular modal field is forced

Physical Review Applied
We combine soliton dynamics in gas-filled hollow-core photonic crystal fibers with a state-of-the-art fiber laser to realize a turnkey system producing few-femtosecond pulses at 8-MHz repetition rate at pump energies as low as 220 nJ. Furthermore, by

Optical nonreciprocity, which breaks the symmetry between forward and backward propagating optical waves, has become vital in photonic systems and enables many key applications. So far, all the existing nonreciprocal systems are implemented for linea

We report a nonreciprocal reconfigurable light-driven isolator for vortex modes based on topology-selective Brillouin scattering in chiral PCF. The isolation rates are higher than 22 dB and 23 dB for 1st- and 2nd-order optical vortices.

We report supercontinuum generation in chiral, thus circularly birefringent, all-normal dispersion fibers, where low noise can be achieved for pumping along the slow as well as the fast axis due to suppression of coherent coupling.
