Spatio-temporal dynamics and coherent control of quantum cascade laser frequency combs
 Konečný, Aleš ; Souza, Patricia Lustoza de (oponent) ; Detz, Hermann (vedoucí práce)
Quantum cascade laser frequency combs are promising candidates for novel miniaturized spectrometers without any moving parts. They can be generated in the self-starting regime by an interplay of different nonlinearities induced by asymmetrical gain and waveguide dispersion. The available highly optimized tool based on the traveling wave model was used to simulate the self-starting combs. It was further extended by the optical injection locking functionality, the coherent technique of control of frequency combs. Subsequent simulations confirmed locking to the injected signal. Group velocity dispersion (GVD) has been found to have a significant impact on the range of locking. GVD was calculated for the typical device and the frequency comb was optically injection-locked in a detuning range from -2 to 47 MHz.
