All-optical Signal Processing with QD-SOAs

In the framework of a joint research activity (DFG-Sonderforschungsbereich), all-optical signal processing based on quantum-dot SOAs shall be investigated. These novel devices boast several properties that make them potentially ideal for nonlinear optics and all-optical signal processing.


QD-SOAs are fast with very small recovery times. They do not show a direct relationship between gain and phase, which should be advantageous for the processing of phase-modulated signals. Their narrow-band cross-gain modulation provide the chance for simultaneous multi-wavelength processing.
