A 20-year-old man presented with generalized acquired anhidrosis and heat intolerance which was confirmed by a sweat test. Other clinical features included severe pain of the extremities and cutaneous angiokeratomas. On electronmicroscopy, granules specific for Fabry's disease were observed in the endothelial cells.

Lowering backward Raman and Brillouin scattering in waveguide Raman wavelength converters
Background Liquid filled hollow core fiber Raman wavelength converters are devices enabling to red-shift the wavelength of laser beams delivered by either fixed wavelength or tunable lasers. Most of the reported converters operate in a pulsed regime with

Antenna surface plasmon emission by inelastic tunneling
Developing a microscale ultrafast electrical source of surface plasmons is crucial for nanophotonic applications. Here, the authors report the design, fabrication and characterization of nanoantennas for emission and control of surface plasmons by ...

Polarization conversion with a photonic crystal slab [PDF]
We show that a photonic crystal slab can enable efficient polarization conversion. Two mechanisms are identified. The first mechanism relies on the anisotropy of the bulk properties of the metamaterial and is mediated by interferences.

Role of Static Modes in Quasinormal Modes Expansions: When and How to Take Them into Account?
The scattering of electromagnetic waves by a resonator is determined by the excitation of the eigenmodes of the system. In the case of open resonators made of absorbing materials, the system is non-Hermitian, and the eigenmodes are quasinormal modes ...

Unlocking Terahertz Steganography: Authentication of Hidden Images in Flexible Media
Hidden information in multilayered devices, such as steganographic portraits, is detected and authenticated using reflection‐mode terahertz time‐domain imaging. Image reconstruction relies on a dedicated figure‐of‐merit obtained by integrating the signal intensity over the time‐window associated with the reflection from the metallic mirror backing the ...

Design of nanofibres for efficient stimulated Raman scattering in the evanescent field [PDF]
Nanofibres can be produced with diameters smaller than the wavelength of the light they guide. In this regime, the guided mode presents a strong evanescent field well adapted to the excitation of “evanescent nonlinearities”.

Deterministic Transferable Planar Dielectric Mirrors for Investigating Strong Light–Matter Coupling
Transferable dielectric distributed Bragg reflectors enable the deterministic assembly of high‐quality planar microcavities while maintaining the intrinsic properties of quantum materials during fabrication. The resulting structures exhibit robust exciton‐photon coupling in monolayer WS2${\rm WS}_{2}$ from cryogenic to room temperature, establishing a ...

Experimental demonstration of a temporal pulse shaping method based on nonlinear chirp [PDF]
We present a general temporal shaping method based on spectral phase-only modulation for ultrafast laser sources. We explain the working principle of this technique and use it experimentally to generate a ramp-shaped pulse at the output of a laser source
