We exploit a ~350nm-thick GaAs/Al0.2Ga0.8As multi-quantum-well heterostructure to demonstrate heterodyne detection at 10.3um wavelength with a…
Optically-driven photoconductive switches are one of the predominant sources currently used in terahertz imaging systems. However,…
Second-order optical nonlinearities can be enhanced by orders of magnitude in resonantly excited nanostructures. However, they…
Harmonic modelocking of lasers is usually employed to attain high repetition rates. Despite the favourable dynamics…
