Photonic Crystal Fibers (PCF) play a crucial role for fundamental investigations such as acousto-optical interactions as well as for applications, such as distributed sensors. One limiting factor for these experiments is the fiber inhomogeneity owing to th ...
Photonic crystals are periodic dielectric structures having periodicity of the order of the wavelength. Consequently, they offer the ability to control the propagation of electromagnetic waves in a similar way as the periodic potential aspects the electron ...

We present a novel distributed sensing technique that makes possible the observation of Brillouin gain spectral distribution and acoustic decay time in photonic crystal fiber as well as in standard single-mode fiber. ...

We demonstrate that an optical fibre current sensor can measure current over 500 kA with an accuracy of 0.2%. This level of accuracy has never previously been achieved using a traditional non-optical sensor ...
We propose and demonstrate a photonic approach to a reconfigurable channelized radio frequency (RF) receiver for instantaneous RF spectrum monitoring and analysis. Our approach relies on the generation of high quality copies of the RF input by wavelength m ...
We experimentally demonstrate that a novel type of photonic delay line based on movable dynamic grating reflectors generated in polarization maintaining fibers can provide continuously tunable signal delaying for high capacity optical data streams and wide ...
Photonic crystals are periodic dielectric structures, where the periodicity varies in one, two or three dimensions. Analogous to the periodic potential of electrons in semiconductors, the periodic variation of the dielectric constant influences the electro ...
