Abstract

We use a semiconductor optical Bloch equation approach combined with a traveling wave equation for the electric field to explore the effect of noise on the signal quality of a quantum-dot(QD) semiconductor optical amplifier. Using a stochastic white noise source for the spontaneous emission inside the QDs, we can show that there is a tradeoff between amplification performance and signal quality. Nevertheless, optimized operation conditions exist and are discussed for various input signals.

Noise in optical amplifiers

Gianfranco Cariolaro, Roberto Corvaja, Pierluigi Franco +2 more

This article presents an application of a recently published probablistic model for traveling wave optical amplification. Both optical signal and amplified spontaneous emission (ASE) noise are modeled as bunches of photons traveling along the amplifying region with size varying according to simple random rules. The results of the theory enable one to obtain a complete and accurate characterization of the signal and noise counting at the amplifier output. On the basis of the above statistics, we find a realistic evaluation of the limits imposed by both quantum and ASE noise on the performances of a receiver including an optical amplifier at a preamplifier stage.

On the noise properties of linear and nonlinear quantum-dot semiconductor optical amplifiers: the impact of inhomogeneously broadened gain and fast carrier dynamics

A. Bilenca, G. Eisenstein

We present a detailed analytical model describing the noise properties of quantum-dot (QD) optical amplifiers operating in the linear and saturated regimes. We describe the dependence of the optical noise on the main physical parameters characterizing the QD gain medium as well as on operating conditions. The optical noise at the amplifier output shows a broad-band spectrum with an incoherent spectral hole due to the gain inhomogeneity. A coherent spectral dip stemming from noise-signal nonlinear interactions is superimposed on that broad-band spectrum. The broad-band incoherent component is also calculated using an approximate model which makes use of an equivalent inhomogeneous population inversion factor. The validity of the approximation is examined in detail. We also calculate the electrical relative intensity noise and observe a spectral hole corresponding to the spectral shape of the optical noise. The most important characteristics of the optical and electrical noise spectra are determined by the degree of inhomogeneous broadening and by the fast carrier dynamics of QD amplifiers. The fast dynamics causes a very wide noise spectral hole which has important potential consequences for detection of fast data and for all optical signal processing.

Gain dynamics and saturation in semiconductor quantum dot amplifiers

T.W. Berg, Jesper Mørk, J. M. Hvam

Quantum dot (QD)-based semiconductor optical amplifiers offer unique properties compared with conventional devices based on bulk or quantum well material. Due to the bandfilling properties of QDs and the existence of a nearby reservoir of carriers in the form of a wetting layer, QD semiconductor optical amplifiers may be operated in regimes of high linearity, i.e. with a high saturation power, but can also show strong and fast nonlinearities by breaking the equilibrium between discrete dot states and the continuum of wetting layer states. In this paper, we analyse the interplay of these two carrier populations in terms of a simple rate equation model. Based on the steady-state and small-signal properties of the model, we analyse and discuss the optical modulation response and the four-wave mixing properties of QD semiconductor optical amplifiers, in particular emphasizing the role of ultrafast gain dynamics.

Ground and excited-state performance of an quantum-dot semiconductor amplifier

Benjamin Lingnau, Eckehard Schöll, Kathy Lüdge

Using an optimized delay-differential-equation model, we efficiently simulate the signal propagation through a quantum-dot semiconductor amplifier. We analyze the device performance by means of the signal quality factor when amplifying signals on either the ground or excited state transition, in dependence of pump current and signal power.

Analytical description of gain depletion and recovery in quantum dot optical amplifiers

Ermin Malić, Marten Richter, Gregor Hartmann +3 more

We present an analytical description of ultrashort femtosecond pump–probe experiments and investigate the gain response of quantum dot (QD) semiconductor optical amplifiers. The calculation provides a full analytical solution of numerical studies to recent experiments in such structures (Gomis-Bresco et al 2008 Phys. Rev. Lett. 101 256803). Our approach is based on QD Bloch equations, which are analytically evaluated within the third-order temporal perturbation theory (χ (3) level). In particular, we study the influence of the coherence and the population dynamics of two confined QD levels on the gain as a function of the delay time between the pump and the probe pulse. We discuss how to engineer optimal conditions for high-performance QD amplifiers, which are characterized by an ultrafast gain recovery and a pronounced gain depletion.

Design of optical pumping scheme for quantum‐dot semiconductor optical amplifiers

Hussein Taleb, Kambiz Abedi

In this study, design of optical pumping (OP) scheme for quantum‐dot semiconductor optical amplifiers (QD‐SOAs) is investigated. To evaluate the static and dynamic responses of the QD‐SOA under OP, a non‐linear state‐space model is derived in which the effects of the homogeneous and inhomogeneous broadening of the gain medium and the spectral dependence of the input signals are taken into account. Using this model, the effects of the wavelength and power of the pump signal and the homogeneous and inhomogeneous linewidths are studied in detail. Simulation results demonstrate that optimal operation of the QD‐SOA under the OP scheme is realised if the detuning between the pump wavelength and the input signal wavelength is constant (around 100 nm for our investigated device). The authors found that OP scheme can be employed for non‐linear signal processing applications, where the superiorities of the OP against the electrical pumping appear for small values of the homogeneous and inhomogeneous linewidths.
