We developed a new model for bit error rate in optical communication systems. This model accurately calculates sensitivity for quantum-limited receivers, achieving 33.9 photons/bit for non-return-to-zero format.

Area of Science:

  • Optical communication systems engineering
  • Photonics and optical physics
  • Information theory and coding

Background:

  • Accurate bit error rate (BER) calculation is crucial for designing high-performance optical communication systems.
  • Intersymbol interference (ISI) and detector noise significantly impact BER in direct detection systems.
  • Optically preamplified receivers offer enhanced sensitivity but require sophisticated modeling.

Purpose of the Study:

  • To introduce a novel, accurate model for calculating the bit error rate (BER) in optical communication systems.
  • To incorporate the effects of intersymbol interference (ISI) into the BER calculation model.
  • To determine the sensitivity of a quantum-limited receiver for a specific modulation format.

Main Methods:

  • Developed a theoretical model based on the Laguerre photon-count probability distribution.
  • Applied the model to on-off keying (OOK) intensity modulation with optically preamplified direct detection.
  • Analyzed the impact of intersymbol interference (ISI) on the bit error rate.

    • Main Results:

    • The novel model accurately calculates the bit error rate (BER) for the specified optical communication system.
    • The model successfully accounts for intersymbol interference (ISI) effects.
    • Achieved a precise sensitivity value of 33.9 photons/bit for a quantum-limited receiver using a non-return-to-zero (NRZ) modulation format.

    Conclusions:

    • The presented Laguerre photon-count distribution model provides an accurate method for BER calculation in optically preamplified systems.
    • The model's ability to include ISI enhances its applicability to real-world communication scenarios.
    • The obtained sensitivity value represents a significant benchmark for quantum-limited optical receivers.
