Implication

Experimental study demonstrates high-speed transmission of stable optical solitons over 22 kilometers, indicating scalable methods for ultrafast optical communications.

Key Points

  • To generate and transmit high-repetition-rate optical solitons in the gigahertz regime using a directly modulated distributed-feedback laser diode and optical amplifiers.
  • Generated 6–24-GHz, 17-psec transform-limited optical pulses using a directly modulated distributed-feedback laser diode paired with a narrow-band spectral filter.
  • Boosted signal power into the soliton regime for dispersion-shifted fibers using erbium-doped optical fiber amplifiers.
  • Transmitted generated solitons over a 22-km dispersion-shifted optical fiber link.
  • Achieved average optical power exceeding 10 mW at 6 GHz, yielding a peak power of 98 mW sufficient for soliton formation in dispersion-shifted fiber.
  • Maintained original 17-psec pulse widths completely over a 22-km transmission distance without pulse broadening.
  • Observed soliton-narrowing effects and the splitting of higher-order solitons at increased power levels.
