- ItemSampling techniques applicable for the characterization of the quality of self pulsations in semiconductor lasers(Berlin : Weierstraß-Institut für Angewandte Analysis und Stochastik, 2002) Radziunas, MindaugasThe aim of the presented report is to demonstrate how the sampling techniques can be used to characterize the quality of self pulsations in a multi-section semiconductor laser and the synchronization of self pulsations with an optical or electrical periodically modulated signal. The developed tools are described and some examples are given.
- ItemSemiconductor mode-locked lasers with coherent dual mode optical injection: Simulations, analysis and experiment(Berlin : Weierstraß-Institut für Angewandte Analysis und Stochastik, 2015) Arkhipov, Rostislav M.; Habruseva, Tatiana; Pimenov, Alexander; Radziunas, Mindaugas; Huyet, Guillaume; Vladimirov, Andrei G.Using a delay differential equations model we study the dynamics of a passively modelocked semiconductor laser with dual frequency coherent optical injection. The locking regions where the laser pulse repetition rate is synchronized to the separation of the two injected frequencies were calculated numerically and measured experimentally. Asymptotic analysis performed in the limit of the small injection field amplitude revealed the dependence of the locking regions on the model parameters, such as optical bandwidth, absorber recovery time and linear losses.
