The first concrete connection between non-linear optical effects, such as the supercontinuum generation, and photoionization was established by A . Brodeur and S . L . Chin [ ref 4 ] in 1999, based on optical experimental data and modeling.

While supercontinuum generation has for long been the preserve of fibers, in recent years, integrated waveguides have come of age to produce extremely broad spectra, opening the door to more economical, compact, robust, scalable and mass-producible supercontinuum sources.

His discovery of the white-light supercontinuum laser is at the root of optical coherence tomography, which is breaking barriers in ophthalmology, cardiology, and oral cancer detection ( see " Better resolution with multibeam OCT, " page 28 ) among other applications.

As an example, an LCoS-based Programmable Optical Processor ( POP ) has been used to broaden a mode-locked laser output into a 20 nm supercontinuum source whilst a second such device was used to compress the output to 400 fs, transform-limited pulses.

For this reason, xenon arc lamps of smaller sizes, down to 10 watts, are used in optics and in precision illumination for microscopes and other instruments, although in modern times they are being displaced by white light supercontinuum lasers which can produce a truly diffraction limited spot.

Their research included : using a supercontinua to measure the group velocity dispersion in optical fibres; the demonstration of a 1 Tbit / s based WDM system; and more recently a 1000 channel dense wavelength division multiplexed ( DWDM ) system capable of 2.8 Tbit / s using a supercontinuum fractionally more than 60 nm wide.

Other areas of development since 2000 have included : supercontinua sources that operate in the picosecond, nanosecond and CW regimes; the development of fibres to include new materials, production techniques and tapers; novel methods for generating broader continua; novel propagation equations for describing supercontinuum in photonic nanowires, and the development of numerical models to explain and aid understanding of supercontinuum generation.

Early on, while working on optical phonon lifetimes, the basis for his doctoral thesis, he accidentally discovered the white-light supercontinuum laser . " I thought there was something wrong with the experiment, " he said . " For three months I worked to find the source of my error, because what I was seeing just didn't seem possible . " He jokes that he used up a lot of black masking tape trying to seal the spectrograph that he assumed was leaking light.
