In this review, we introduce photonic crystal fibre as a novel optofluidic microdevice that can
be employed as both a versatile chemical sensor and a highly efficient microreactor. We …

Supercontinuum sources are all-fiber pulsed laser-driven systems that provide high power
spectral densities within ultra-broadband spectral ranges. The tailored process of generating …

Broadband spectroscopy is an invaluable tool for measuring multiple gas-phase species
simultaneously. In this work we review basic techniques, implementations, and current …

We demonstrate the generation of a supercontinuum in a 2 cm long silicon wire by pum**
the wire with mid-infrared picosecond pulses in the anomalous dispersion regime. The …
