“…The reason is that the ratio of the distribution of the constant gain in the semiconductor to each longitudinal mode randomly changes temporally because many modes compete. This intensity noise is called the mode distribution noise [14,15]. As the longitudinal mode separates from the center of the oscillation spectrum, the RIN of the longitudinal mode tended to increase.…”

SUMMARYTo understand the fluctuations in laser output pulses, information about the longitudinal linewidth forming the pulses and the relative intensity noise (RIN) is very important. In this paper, we conducted detailed measurements of the linewidth and RIN in the oscillating longitudinal mode of a mode-locked laser diode (MLLD) having different fabrication methods for the repetition frequencies of 10 and 40 GHz. The results are a longitudinal linewidth of several megahertz to gigahertz, a constant linewidth exhibiting the longitudinal mode independence, and a larger RIN as the distance from the center of the oscillation spectrum increases.

“…MPN has been studied extensively in [17]. MPN is a phenomenon occurring because of an anti-correlation among pairs of longitudinal modes, that is, even though the total intensity of the modes remains relatively constant, various longitudinal modes fluctuate in such a way that individual modes exhibit large intensity fluctuations [8].…”

“…According to the statistical analysis of MPN presented in [17,18], MPN penalty in nearly single-mode lasers will lead to independent (random) errors. We can then use (2), (3), and (5) to estimate the theoretical bound when RS(255, 239) codes are employed to correct for the power penalty introduced by the MPN in the channel.…”

We experimentally demonstrate the performance analysis of burst-mode receivers (BMRx) in a 622 Mb/s 20-km gigabit-capable passive optical network (GPON) uplink. Our receiver features automatic phase acquisition using a clock phase aligner (CPA), and forward-error correction using (255, 239) Reed-Solomon (RS) codes. The BMRx provides instantaneous (0 preamble bit) phase acquisition and a packet-loss ratio (PLR) \ 10 -6 for any phase step (±2p rads) between consecutive packets, while also supporting more than 600 consecutive identical digits (CIDs). The receiver also accomplishes a 3-dB coding gain at a bit-error rate (BER) of 10 -10 . The CPA makes use of a phase picking algorithm and an oversampling clock-and-data recovery circuit operated at 29 the bit rate. The receiver meets the GPON physical media dependent layer specifications defined in the ITU-T recommendation G.984.2 standard. We investigate the PLR performance of the system and quantify it as a function of the phase step between consecutive packets, received signal power, CID immunity, and BER, while also assessing the tradeoffs in preamble length, power penalty, and pattern correlator error resistance. We also study the impact of mode-partition noise in the GPON uplink in terms of the effective PLR and BER coding gain performance of the system. In addition, we demonstrate how the CPA and the RS(255, 239) codes can be used in tandem for dynamic burst-error correction giving reliable BERs in bursty channels.

“…For small values of dispersion, (9) states that EMPN is proportional to the noise spectral density of the individual modes, noise frequency, and dispersion. Doubling any term doubles noise intensity, increasing EMPN spectral density by 6 dB at the photodetector output.…”

A simple model describing the change in modepartition noise as a function of modulating frequency, modulation depth, and dispersion in a microwave SCM, fiber optic transmission system is presented with experimental verification. The effects of temperature on laser intensity and mode-partition noise are also explored. Longitudinal mode distribution associated with low and high noise levels are identified.
