Fast optoelectronic switch has high sensitivity

Researchers at IMEC (Leuven, Belgium) and Vrije Universiteit Brussel (Belgium) developed an AlGaAs/GaAs device that acts as an optoelectronic switch at speeds as high as 16 MH¥and is sensitive to opticalenergy differences as low as 250 fJ. In other words, the device completed a switching cycle in 60 ns, switching correctly when exposed to energydensity differences as low as 0.21 fJ/µm2.

Large-scale simulations demonstrate that chaos is responsible for stochastic heating of dense plasma by intense laser energy. This image shows a snapshot of electron distribution phase space (position/momentum) from the dense plasma taken from PIC simulations, illustrating the so-called 'stretching and folding' mechanism responsible for the emergence of chaos in physical systems.
