Abstract:
Gain saturation in a semiconductor optical amplifier with an array of quantum dots was studied analytically and by numerical simulation on the basis of an analysis of the rate equations. It is shown that, at a moderate injection level, the saturation power increases in proportion to the current density, and then reaches its maximum value, limited by the rate of capture of charge carriers to the ground state and by the number of quantum dots interacting with photons. Expressions are proposed that allow an explicit description of the dependence of the saturation power on the current and its relationship with the internal parameters of the active region.
Keywords:
semiconductor optical amplifier, quantum dots, rate equations.
