We present a new type of compact and all-glass based vapour cell integrating hollow-core photonic crystal fibres. The absence of metals, as in a traditional vacuum chamber and the much more compact geometry allows for fast and homogeneous heating. As

Nowadays fiber biphoton sources are nearly as popular as crystal-based ones. They offer a single spatial mode and easy integrability into optical networks. However, fiber sources lack the broad tunability of crystals, which do not require a tunable p

Knowledge of the phase and amplitude of an optical field is of critical importance in many applications, for example in measuring the carrier envelope phase of an ultrashort pulse. While the intensity spectrum can easily be obtained using a spectrome

Non-classical correlated twin beams can be generated through the modulational instability in a hollow-core photonic crystal fibre filled with a noble gas. Since the gain is provided by a monatomic gas, the influence of Raman effect, which is typical

We report non-destructive measurement of the diameter of submicron air-clad waveguides to nanometer precision, based on parametric amplification of a broadband seed signal. Ultrashort pump and seed pulses allow the diameter to be longitudinally resol

Four-wave mixing in Ar-filled sub-micron suspended-core fibres is used to generate spectrally tunable entangled photon pairs. A continuous shift of 0.30 THz/bar is measured for the generated sidebands with a coincidence-to-accidental ratio over 104.
