“…2 With the DST technique the relative intensity noise (RIN) resulting from the phase modulation (PM) to TM conversion of laser phase noise can be a major impairment. 4 Since the fiber nonlinearity can cause a significant enhancement of RIN due to the enhancement of the PM-IM conversion,5 the impairment due to laser phase noise in DST systems is expected to be strengthened.…”

This paper investigates the influence of laser phase noise in dispersion supported transmission systems performance. It is shown that the relative intensity noise enhancement at fiber output due to fiber nonlinearity, observed in the anomalous propagation regime, can reduce considerably the maximum transmission distance achievable by dispersion supported transmission systems operated at 2OGbit/s. The results indicate that for a power at fiber input of 10mW, the maximum transmission distance achievable by dispersion supported transmission systems operated at 2OGbitJs is reduced from about 70km to 48km when the influence of laser phase noise is taken into account. The influence of laser phase noise in intensity modulated with direct detection systems performance operated at 2OGbit/s is also assessed and compared with the correspondent dispersion supported transmission systems operated at the same bit rate. The results indicate that dispersion supported transmission systems are much more sensitive to laser phase noise, than the intensity modulated with direct detection systems.

“…A better way to estimate this parameter is from RIN (relative intensity noise) measurements, but these were not available. This parameter is very important since it was shown [31] that the contribution due to frequency-to-intensity conversion of laser phase noise, after propagation via dispersive fibres, is responsible for the BER floor observed in DST experiments at 10 Gbit/s for distances around 253 km SMF [32]. However, at 20 Gbit/s the maximum link length is less than 80 km (see section 4), and no BER floors (close to 10 -9 ) have been observed in our simulations even with this slightly higher value of β sp .…”

In this paper, a set of multiple-quantum-well (MQW) laser parameters is proposed for simulation of optical transmission systems at 20 Gbit/s. The parameters have been estimated by joint fitting of a small signal intensity modulation (IM) response model to five measured IM response curves of a strained layer MQW laser, using the Levenberg-Marquardt method. Good agreement between theoretical and experimental curves was obtained. Using these laser parameters, we have assessed the performance of dispersion supported transmission systems at 20 Gbit/s incorporating an erbium doped fibre amplifier (EDFA) or a semiconductor optical amplifier (SOA) as a booster amplifier. It is shown that the use of a SOA, with an unsaturated gain of 20 dB, improves the system performance for link lengths ranging from 8 to 20 km of standard single-mode fibre (SMF) due to partial chirp compensation in the SOA, and degrades the system performance between 1.2 and 2.5 dB for link lengths ranging from 30 to 50 km. The increase of the unsaturated gain of the SOA from 20 to 25 dB is only advantageous for link lengths ranging from 8 to about 12.5 km where a small performance improvement, less than or equal to 0.8 dB, is observed. The influence on the system performance of an increase of the laser line width enhancement factor from 2 to 3 is also investigated.

“…It is suggested that a laser with a narrow linewidth should exhibit much less phase-noise-to-intensity-noise conversion than those with a large linewidths. This feature greatly reduces the RIN enhanced by chromatic dispersion and beating inside the photo-detectors [20]. In comparison with sliced ASE injected FPLD proposed in [10], [17], the CW light seeded FPLD could achieve a better direct-modulation performance and a larger bandwidth.…”

Abstract-In this work, for the first time, we propose a dualband WDM-PON architecture that enables efficient non-overlapping wavelength reuse and mitigates bidirectional transmission impairments. Weak-resonant-cavity Fabry-Perot laser diodes (WRC-FPLDs) with gain spectra across C-and L-bands are implemented to achieve desirable colorless, uncooled, and inexpensive ONUs. The side mode suppression ratio and modulation performance of the injection-locked WRC-FPLDs with operational wavelengths from 1550 nm to 1580 nm are studied. 25-km transmission experiments have been demonstrated, where the injection-locked WRC-FPLDs are directly modulated with up to 5-Gbit/s OOK upstream signals. Improved signal quality with bit-error rates lower than 10 -9 is obtained which confirms that the dual-band architecture with wavelength sharing can be a potential candidate for future WDM-PON deployments.
