“…Moreover, they did not differentiate the individual contributions of the intrinsic fluctuations and bit pattern. 10,11 Most recently, the authors showed that the bit-pattern induced TOJ is enhanced when the bit slot of a NRZ bit stream is shorter than the setting time of the relaxation oscillations. 12 When the semiconductor laser is biased near threshold, the TOJ is mainly a bit-pattern effect, whereas the intrinsic noise dominates at high bias levels.…”

This paper presents theoretical evaluation of the digital modulation performance of semiconductor lasers in digital communication systems with gigabit rates. The study is based on numerical integration of the rate equations augmented by a nonreturn-to-zero ͑NRZ͒ bit generator. For solitary semiconductor lasers, the performance is evaluated in terms of the eye diagram, turn-on delay jitter ͑TOJ͒, and signal-to-noise ratio. In communication systems, the performance is evaluated by the bit error rate ͑BER͒ and power penalty induced by the laser noise. Contributions of both the intrinsic fluctuations and bit pattern to the TOJ and BER are assessed. The results show that when the modulation current is low and the semiconductor laser is biased relatively above threshold, the power penalty decreases although the eye diagram is not well open. When the modulation current is high enough, biasing the semiconductor laser far-above threshold achieves both lower power penalty and higher eye-diagram quality.

“…These potential fluctuations modulate that part of the carriers that recombines in quantum wells and produce photons. LD radiation spectrum and mode competition strongly depends on the laser resonator quality and back reflected light (Agrawal & Shen, 1986). Therefore influence of the laser facet reflectivity on the noise characteristics and mode-hopping effect has been investigated (Palenskis et al, 2003).…”

A unified model for the noise in a single-mode fiberoptic communication system incorporating modal noise, shot noise and circuit noise is presented. The bit error degradation arising from modal noise is evaluated for 2Gbit/s digital fiberoptic system and the power penalties necessary to compensate for the presence of modal noise have been calculated as a function of the splice loss and the loss parameter of the LP U mode. These calculations will be useful in the system design for long distance optic systems.
