Multiple exciton generation and ultrafast exciton dynamics in HgTe colloidal quantum dots

Ali Al-Otaify, Stephen V. Kershaw, Shuchi Gupta, Andrey L. Rogach, Guy Allan, Christophe Delerue, David J. Binks

The investigation of sub-nanosecond exciton dynamics in HgTe colloidal quantum dots using ultrafast transient absorption spectroscopy is reported. The transmittance change spectrum acquired immediately after pumping is dominated by a bleach blue-shifted by ∼200–300 nm from the photoluminescent...

A fully distributed non linear waveguide using (Pb,Sr)TiO3 thin film : second and third harmonics generation

Freddy Ponchel, Ludovic Burgnies, D. Ducatteau, Eric Lheurette, Denis Remiens, D. Lippens

We report on the experimental investigation of a non-linear (NL) Co-Planar Waveguide (CPW) fabricated by means of a ferroelectric film. In contrast to conventional NL-CPW, periodically loaded by lumped varactors, the tunable ferroelectric material is fully distributed along the propagation...
