Near-Full Current Dynamic Range THz Quantum Cascade Laser Frequency Comb

Near-Full Current Dynamic Range THz Quantum Cascade Laser Frequency Comb

The present study proposes a terahertz quantum cascade laser frequency comb (THz QCL FC) with a semi-insulated surface plasma waveguide characterized by a low threshold current density, high power and a wide current dynamic range. The gain dispersion value and the nonlinear susceptibility were optim...
