ABSTRACT We propose a self-clocking method based on in-band clock pilot insertion at the transmission data signal. The method can achieve clock recovery without the need for an ultrafast phase comparator and a phase-locked loop in the receiver. We demonstrate fast synchronization, low timing jitter, and a highly stable recovered clock from a 160 Gbit/s optical time-division multiplexing data signal after a 51 km fiber transmission. The recovered clock shows no patterning effect with a clock dynamic range of 10 dB for error-free operation of 160 to 40 Gbit/s demultiplexing with a power penalty of 1.1 dB.

    ABSTRACT: In new optical pulse generator using delayed-interference-signal-wavelength-converter (DISC)-type all-optical gate, we injected sinusoidally modulated light to ring cavity. With this way, externally modulated laser oscillation and mode-locked pulse laser oscillation occurred. These generated pulse's widths and repetition frequencies are 27 ps, 10.5 GHz and 2.1 ps, 10.5 GHz, respectively.

    ABSTRACT: A novel incoherent OCDMA receiver with incorporated all-optical clock recovery for self-synchronization of a time gate for the multi access interferences (MAI) suppression and minimizing the effect of data time jitter in incoherent OCDMA system was successfully developed and demonstrated. The solution was implemented and tested in a multiuser environment in an out of the laboratory OCDMA testbed with two-dimensional wavelength-hopping time-spreading coding scheme and OC-48 (2.5 Gbp/s) data rate. The self-clocked all-optical time gate uses SOA-based fibre ring laser optical clock, recovered all-optically from the received OCDMA traffic to control its switching window for cleaning the autocorrelation peak from the surrounding MAI. A wider eye opening was achieved when the all-optically recovered clock from received data was used for synchronization if compared to a static approach with the RF clock being generated by a RF synthesizer. Clean eye diagram was also achieved when recovered clock is used to drive time gating.

    ABSTRACT: Implementing time gating in ultra-high speed OCDMA networks over long distance transmissions will require precise synchronization in order to suppress the influence of timing jitter on the OCDMA receiver. To implement optical gating, an optical clock is needed to control a switching window i.e., “a time gate” to pass the desired autocorrelation peak while blocking the MAI noise. We demonstrate that the use of a network global clock distribution is not necessary if the receiver synchronization is done via optical clock recovery. In our experimental demonstration a wider eye opening with power budget improvement of ~7.5 dB was achieved when using all-optical clock recovery compare to clock distribution.
