Open AccessTwo-photon interference between disparate sources for quantum networking
Quantum networks involve entanglement sharing between multiple users. Ideally, any two users would be able to connect regardless of the type of photon source they employ, provided they fulfill the requirements...

Hollow-core photonic crystal fibres for delivery and compression of ultrashort optical pulses
We describe the use of tapered hollow-core photonic crystal fibres for delivery and compression of ultrashort optical pulses. We demonstrate delivery of transform-limited pulses with less than 100 fs pulse len...

Spectral-temporal soliton dynamics analysis near second zero-dispersion point in photonic crystal fibers
The propagation dynamics of an ultrashort optical pulse near the second zero-dispersion point of a small-core high-delta photonic crystal fiber is investigated using cross-correlation frequency-resolved optica...

Maximization of supercontinua in photonic crystal fibers by using double pulses and polarization effects
We show with sub-20 fs pulses both experimentally and theoretically two techniques to control the width and polarization of spectral supercontinua generated in photonic crystal fibers. The first exploits doubl...

Generation of a spectrally asymmetric third harmonic with unamplified 30-fs Cr:forsterite laser pulses in a tapered fiber
Unamplified subnanojoule 30-fs pulses of Cr:forsterite laser radiation are shown to generate the third-harmonic signal in a tapered fiber. Analysis of the dispersion properties of a tapered fiber indicates the...

Two-octave spectral broadening of subnanojoule Cr:forsterite femtosecond laser pulses in tapered fibers
Spectral broadening of femtosecond Cr:forsterite laser pulses is enhanced due to the use of tapered fibers. Supercontinuum generation with unamplified subnanojoule femtosecond Cr:forsterite laser pulses is obs...

Efficient distributed feedback solid state dye laser with a dynamic grating
We present the first operation of a distributed feedback solid state dye laser with a dynamic, pump-induced grating. Broadly tunable, narrow band operation in the region of 616 nm (604–649 nm) has been demonst...

The basalts of Réunion Island, Indian Ocean
Réunion consists of two shield volcanoes, Piton des Neiges (3069 m) and Piton de la Fournaise (2631 m). The former is extinct and deeply eroded, so that its internal structure is clearly displayed. The deepest...
