摘要： Methods for significant reduction of beat noise in incoherent optical spread spectrum communication system are disclosed. In one embodiment, we use the spectral broadening of an incoherent signal, which can be achieved with some non-linear effects as the four-waves mixing a saturated semiconductor optical amplifier. In the second embodiment, we present a new method to eliminate the bit error floor for optical systems using incoherent broadband sources based on an all-optical wavelength conversion of an incoherent optical signal to a coherent optical signal using the cross-gain modulation in semiconductor optical amplifiers. This conversion can affect positively and reduce significantly the beat noise in optical spread-spectrum communication system and can be used as an all-optical wavelength conversion process for optical signals from last miles system using spread-spectrum sources to an aggregate WDM networks. In the second field of the invention, OCDMA transmitters and receivers using Semiconductor Optical Amplifier are presented. The OCDMA transmitter includes the generation of a broadband pulse train, the encoding with the appropriate user encoder and the modulation with its proper data. In one embodiment, the modulation is done after the generation of a broadband pulse train that can be shared by several users in this case. In the other embodiment, the modulation can be done directely by monitoring the electrical bias of SOA.

摘要： An encoding/decoding device for OCDMA communications with an optical network is provided. The device uses a single reflecting element to perform both the encoding of outgoing signal and the decoding of incoming signal. A directional optical assembly allows to differentiate the origin of the signals to forward the outgoing signals after encoding to the network and the incoming signals after decoding to a receiver.
