Intensity noise in semiconductor lasers coupled to Fiber Bragg Grating

摘要

Stationary characteristics and relative intensity noise are simulated for a laser diode with strong filtered optical feedback from an external Bragg reflector. Multiple reflections in external cavity are taken into account through the introduction of Green functions. An analysis of the stationary solutions shows the appearance of new solutions for strong feedback and collapse in the plane frequency-gain of the ellipse which usually contains the modes and so-called antimodes. Numerical results are compared with analytical expressions.
