  • Feedback Sensitivity of Detuned DBR Semiconductor Lasers 
    TRONCIU, Vasile; WERNER, Nils; WENZEL, Hans; WÜNSCHE, Hans-Jürgen (IEEE, 2021)
    A distributed Bragg reflector (DBR) laser represents a simple realization of a semiconductor laser operating in a single longitudinal mode. We present a so far missing theoretical study how its reflection tolerance depends ...
  • Improving the spectral performance of extended cavity diode lasers using angled-facet laser diode chips 
    KRÜGER, Mandy; TRONCIU, Vasile Z.; BAWAMIA, Ahmad; KÜRBIS, Christian; RADZIUNAS, Mindaugas; WENZEL, Hans; WICHT, Andreas; PETERS, Achim; TRÄNKLE, Günther (Springer Nature Switzerland, 2019)
    We present and compare theoretical and experimental results on the electro-optical performance of extended cavity diode lasers (ECDLs) that employ two ridge waveguide designs for the single-transverse mode GaAs laser diode ...
  • Investigation of red-emitting distributed Bragg reflector lasers by means of numerical simulations 
    TRONCIU, Vasile Z.; WENZEL, Hans; RADZIUNAS, Mindaugas; REGGENTIN, Matthias; WIEDMANN, Jörg; KNIGGE, Andrea (The Institution of Engineering and Technology, 2018)
    The authors report theoretical and experimental results on the properties of distributed Bragg reflector semiconductor lasers. Using the traveling wave equation model, they show that a proper choice of coupling coefficient ...
  • Mode transitions in distributed-feedback tapered master-oscillator power-amplifier: theory and experiments 
    RADZIUNAS, Mindaugas; TRONCIU, Vasile Z.; BANDELOW, Uwe; LICHTNER, Mark; SPREEMANN, Martin; WENZEL, Hans (Springer Nature Switzerland, 2008)
    Theoretical and experimental investigations have been carried out to study the spectral and spatial behavior of monolithically integrated distributed-feedback tapered master-oscillators power-amplifiers emitting around 973 ...
  • Study of Microintegrated External-Cavity Diode Lasers: Simulations, Analysis, and Experiments 
    RADZIUNAS, Mindaugas; TRONCIU, Vasile Z.; LUVSANDAMDIN, Erdenetsetseg; KÜRBIS, Christian; WICHT, Andreas; WENZEL, Hans (IEEE, 2015)
    This paper reports the results of numerical and experimental investigations of the dynamics of an external-cavity diode laser device composed of a semiconductor laser and an external Bragg grating, which provides optical ...
