Engineering the spectral bandwidth of quantum cascade laser frequency combs
Maximilian Beiser, Nikola Opačak, Johannes Hillbrand +2
Quantum cascade lasers (QCLs) facilitate compact optical frequency comb sources that operate in the mid-infrared and terahertz spectral regions, where many molecules have their fun…

Frequency comb generation by Bloch gain induced giant Kerr nonlinearity
Nikola Opačak, Sandro Dal Cin, Johannes Hillbrand +1
Optical nonlinearities are known to provide a coherent coupling between the amplitude and phase of the light, which can result in the formation of periodic waveforms. Lasers that e…
