摘要： An active structure in the semiconductor die of an amplifier or converter includes a plurality of stacked active layers with different compositions. The different compositions lead to a spectral offset between the respective gain bands of the layers which widens the gain band of the amplifier or the optical bandwidth of the converter. Applications include fiber optic telecommunication networks.

摘要： In order to be able to use a semiconductor light amplifier of conventional type and operating under gain saturation conditions while nevertheless providing constant gain for an optical signal to be amplified, the device comprises means for producing a compensation light wave and coupling means for injecting the optical signal to be amplified and the compensation light wave into the amplifier. The compensation light wave presents amplitude modulation such that when combined with the optical signal to be amplified the overall amplitude modulation is eliminated or at least attenuated. The device is applicable to optical transmission systems operating at a single wavelength or with wavelength division multiplexing.

摘要： A ring optical transmission network access node (ANi) comprises: two identical band splitters (BSa, BSb), each provided with homologous first, second and third ports (Ba, BWa, BPa; Bb, BWb, BPb), a first coupler (CW) coupling the second port (BWb) of the second splitter (BSb), on the one hand, to the second port (BWa) of the first splitter (BSa) via a first channel and, on the other hand, to an access point (A2) via a second channel, a second coupler (CP) coupling the third port (BPa) of the first splitter (BSa), on the one hand, to the third port (BPb) of the second band splitter (BSb) via a first channel and, on the other hand, to another access point (A1) via a second channel. Such nodes enable the implementation of a passive ring network comprising only one fiber and in which the coupling ratios of the couplers (CW, CP) are optimized for two opposite traffic propagation directions.Application in particular to optical fiber metropolitan access networks, with broken fiber protection device.

摘要： A WDM network (R) comprises an optical fiber (F) connected to a hub (H) via an input of a demultiplexer (DX) having N outputs to communications stations (Si-Sn) able to deliver and/or receive spectral multiplexes of modulated optical signals with different wavelengths, via coupling means (CP, CP′, MXB). The communications stations (Sn−1) are adapted to deliver spectral multiplexes of modulated optical signals from a given one of P disjoint bands of wavelengths. At least one of the coupling means (MXB) is a 2×1 band multiplexer comprising i) an output connected to a downstream portion of the optical fiber (F), ii) a first input connected to one of the stations (then referred to as the “primary” station) and adapted to its band of wavelengths, and iii) a second input connected to an upstream portion of the optical fiber (F) and adapted to channels having wavelengths different from those of the channels passing through the first input. The demultiplexer (DX) is of periodic type so as to deliver at each of its N outputs channels whose wavelengths belong to distinct sets of P wavelengths each belonging to a distinct one of the P disjoint bands.
