Abstract

Dynamical properties of cross-gain modulation (XGM) within the inhomogeneously broadened gain spectrum of an InP quantum dash optical amplifier operating at 1550 nm are examined. The small-signal XGM modulation bandwidth increases with the carrier escape time, which is achieved at long probe wavelengths. The nature of the XGM dynamics is confirmed by spectrally resolved optical modulation response measurements in quantum dash lasers.

Ultrafast cross saturation dynamics in inhomogeneously broadened InAs/InP quantum dash optical amplifiers

Amir Capua, G. Eisenstein, Johann Peter Reithmaier

We describe multiwavelength pump probe characterization of an inhomogeneously broadened semiconductor nanostructure gain medium. An InAs/InP quantum-dash optical amplifier is perturbed by a 100 fs pulse and the response is measured at wavelengths outside the homogeneously broadened spectral region. Energy dependent carrier cross relaxation as well as capture and escape processes are investigated and quantified.

Spectral characteristics of gain and noise saturation in nonlinear InAs/InP quantum dash optical amplifiers

Gain and noise saturation spectra of quantum-dash optical amplifiers were measured to be asymmetric due to the inhomogeneous gain and their quantum wire like nature. Direct measurement of the homogeneously broadened gain bandwidth yields 15 nm.

Specific Features of XGM in QD-SOA

Yossef Ben Ezra, Boris I. Lembrikov, M. Haridim

The peculiarities of a cross-gain modulation (XGM) in quantum-dot semiconductor optical amplifiers (QD SOAs) related to the inhomogeneous broadening are theoretically studied. We have solved numerically the electron rate equations for the QD SOA model including an excited state, a ground state and a continuum wetting layer (WL), and the propagation equations for the pump and the signal lightwaves. It is shown that XGM in QD SOA is possible for a comparatively large detuning close to the inhomogeneous broadening because in such a case QDs with substantially different resonant frequencies interact directly through WL.

Carrier dynamics in inhomogeneously broadened InAs/InP quantum-dot optical amplifiers

Ouri Karni, K. J. Kuchar, Amir Capua +6 more

We report on multi-wavelength pump-probe characterization of the fundamental gain dynamics in recently developed InAs/InP quantum-dot semiconductor optical amplifiers. Recovery of the gain at various wavelengths following a powerful optical pump pulse, was recorded at different bias levels and different excitation powers. Wavelength dependencies of gain saturation depth, of the level to which the gain recovers and of the recovery rates were obtained. Unlike in quantum-dash amplifiers, these quantum-dots exhibit no instantaneous gain response, confirming their zero-dimensional nature.
