Linewidth broadening across a dynamical instability
(Elsevier Science B.V., 1998-12-21)
We investigate experimentally and theoretically the variation of the emission linewidth of an optically-injected semiconductor laser across a resonant period-doubling bifurcation. Close to the dynamical instability, the ...
Lang and Kobayashi phase equation and its validity for low pump
(The International Society for Optical Engineering (SPIE), 1996-05)
An asymptotic theory of Lang and Kobayashi (LK) equations describing a semiconductor laser subject to optical feedback is investigated in detail. We obtain a simple third order, nonlinear, delay-differential equation for ...
