Graphene has been proposed as a particularly attractive material for the achievement of strong optical nonlinearities, in particular generation of terahertz radiation. However, owing to the particular symmetries of the C-lattice, second-order nonline

Researchers demonstrate all-optical wavelength conversion based on a resonant nonlinear process within a terahertz quantum cascade laser. The wavelength of the pump beam (812 nm) corresponds to the interband transitions of the laser. The researchers

We demonstrate broadband coherent THz emission at room temperature from epitaxial graphene under femtosecond optical excitation induced by photon drag effect. We interpret the emitted THz radiation characteristics with a model describing the electron

Injection seeding of terahertz quantum-cascade-lasers with metal-metal waveguides is demonstrated at liquid nitrogen temperatures through injection of phase-locked terahertz pulses. Coherent detection and modelocking of the QCL are demonstrated with

We show the coherent detection of the laser emission from seeded terahertz (THz) quantum cascade lasers (QCL) with metal-metal waveguides using free-space coupling of a THz pulses to the sub-wavelength waveguide. We implement a simple, monolithic pla

Quantum Cascade Lasers are promising sources of Terahertz radiation. Picosecond pulses generation with these lasers is currently at its infancy and their detection is difficult. An intensity electro-optic sampling method is used here to demonstrate 1

Pulses from an actively modelocked terahertz quantum cascade laser are characterized using an optical sampling technique to detect the instantaneous terahertz intensity. Dependence of the pulse width on modulation power and drive current are investig
