  • Analysis of self-pulsation characteristics of InGaN laser diode 
    TRONCIU, V. Z.; YAMADA, Minoru; ABRAM, R. A. (American Physical Society, 2004)
    We report the results of numerical investigations of the dynamical behavior of a blue-violet InGaN laser with a specially incorporated saturable absorber. We have identified the nature of the bifurcation that occurs in the ...
  • Dynamics of a nonlinear ring cavity: Excitability and coherent resonance 
    TRONCIU, V. Z.; ABRAM, R. A.; RUSU, S. S.; BARDETSKIĬ, P. I. (Springer Nature Switzerland, 2007)
    The phenomena of excitability and coherent resonance in a nonlinear ring cavity in the presence of excitons and biexcitons are considered. A bifurcation analysis of the dynamics of the nonlinear ring cavity indicates that ...
  • Excitability of excitons and biexcitons in a ring cavity 
    TRONCIU, V. Z.; ABRAM, R. A. (American Physical Society, 2002)
    We discuss the excitable behavior of excitons and biexcitons in a nonlinear optical ring cavity. The nonlinearity is due to the process of the creation of biexcitons by photon-assisted conversion of excitons. In the ...
  • Ring cavity excitability and coherence resonance. Applications to communication systems 
    TRONCIU, V .Z.; ABRAM, R. A.; RUSU, S. S.; BARDETCHI, P. I. (Technical University of Moldova, 2005)
    We discuss the phenomena of excitability and coherence resonance of a nonlinear ring cavity where excitons and biexcitons are created. A bifurcation analysis of the ring cavity dynamics demonstrates both the existence of ...
  • A theoretical and experimental investigation of the dynamics of tandem blue–violet lasers 
    TRONCIU, V. Z.; YAMADA, Minoru; KAWAKAMI, Toshiyuki; ITO, Shigetoshi; OHNO, Tomoki; TANEYA, Mototaka; ABRAM, R. A. (Elsevier, 2004)
    Theoretical and experimental investigations have been carried out to study the dynamics of blue–violet lasers with two regions that are adjacent in the longitudinal direction. The theoretical results show that both CW and ...
