“…By utilizing the self-feedback of the fiber ring cavity, the WRC-FPLD extends its bandwidth up to four times its original and the receiving sensitivity can even achieve −19.2 dBm which is comparable with the pulsed data generators based on other types of COEOs. For example, our group also applied the gain-switching and electroabsorption-modulator-based COEO systems [33,34] to the pulsed data generation, and the receiving sensitivity is about −20 dBm with the 10 Gb s −1 components. Therefore, it is conjectured that this system configuration proposed with the overclocking WRC-FPLD transmitter can exhibit more advantages with higher bandwidth components or in higher data rate transmission systems.…”

The self-starting and overclocking of a harmonically mode-locked weak-resonant-cavity Fabry-Perot laser diode (WRC-FPLD) with a dual-loop coupled optoelectronic oscillator (COEO) based feedback controller is demonstrated to perform a clock-free pulsed data transmission at 10 Gb s −1 . The WRC-FPLD is considered as the preferred candidate for harmonic mode-locking due to its highly asymmetric cavity architecture, whereby the spontaneous noise can be significantly suppressed without inducing large intra-cavity loss. With the dual-loop COEO configuration, the WRC-FPLD can be boosted to four times of its original modulation bandwidth such that the pulsed carrier quality can be refined. The structure-optimizing principle with the closed-loop model is corroborated by the effective spurious-noise-suppression. The lowest phase noises as low as −100 dBc Hz −1 at 10 kHz with corresponding RMS timing jitter of 0.67 ps are measured. This is achieved by individually inserting 100 and 120 m long single mode fiber segments into two decoupled arms, the dual-loop COEO before the optical receiver pair. The BER performance reaches a minimum with the optimized SMF segment lengths. However, the spurious peaks arise to degrade the BER performance as the phase noise and jitter are inevitably enlarged when inserting longer SMF segments. After modulating the optimized output pulse train with the pseudo-random-bit-sequence data triggered by the same COEO clock, the SNR can achieve 10.9 dB and the receiving sensitivity is −19.2 dBm.
