“…Fig. 2.4(a) shows the typical setup for measuring the small-signal frequency response, from which the fibre dispersion and the chirp parameter of light emitter can be obtained (Devaux et al, 1993). We found that the setup can also be used to determine the length of the wave trains.…”

“…Our earlier measurement of the chirp induced by optical-to-optical (o/o) modulation in an EAM [24], as shown in Fig. 7, suggests a linear variation of the -parameter for reverse voltages lower than 3 V. In this measurement we modified the fiber response method proposed by Devaux [25] by inserting an EAM-based wavelength converter into the transmission line; then the chirp -parameter of the converted signal can be measured with the same principle designed for electrical-to-optical modulation.…”

Abstract-A novel scheme of optical label encoding by wavelength conversion based on electroabsorption modulators (EAMs) is reported. Based on the experimental observations, the chirp properties of the wavelength-converted signal are discussed and a wide dynamic range of the chirp -parameter is found allowed. Compared with cross-gain modulation (XGM) in a semiconductor optical amplifier (SOA), the EAM has several advantages, which make it attractive for optical label encoding or other applications as a wavelength converter.

Abstract-A simple time-domain model for optical pulse propagation in a reflective semiconductor optical amplifier (RSOA) is described. The RSOA saturation energy, effective carrier lifetime and spectral hole-burning parameters used in the model are determined using experimental measurements of the input and output pulse temporal profiles to the RSOA and least mean-square fitting. The model accurately predicts the propagation of 39.6 ps pulsewidth variable energy pulses in the RSOA. The model is used to predict the RSOA gain dynamics, spatial dependence of the pulse shape and dynamic chirp.Index Terms-reflective semiconductor optical amplifier, pulse propagation modeling.
