Abstract: We study a quantum dot light-emitting diodes (QD-LEDs) subject to filtered optical feedback, where the filter is characterized by a mean frequency Omega(m) and a filter width lambda. In the limit of a narrow filter (lambda = 0), the QD-LED equations reduce under some conditions to the equations for a QD-LED with optical feedback, whereas they become the Lang Kobayashi equations in the limit of an unbounded filter width (lambda > 0). Through simulations based on the rate equations for a QD-LED with filtered external optical feedback modes, we show that the output’s nonlinear dynamical system attractors can be controlled through the filter parameters: the filter’s spectral width lambda and its central frequency Omega(m). This is illustrated for a filter-induced global bistability.
