EDFA-Free All-Optical 2R Regeneration Using a Compact Self-Seeded Fabry-Pérot Laser Diode

This study presents an erbium-doped fiber amplifier (EDFA)-free all-optical 2R (reamplification and reshaping) regeneration scheme based on a compact self-seeded Fabry-Perot laser diode. The proposed 2R regenerator achieves a straight line transmission at 10 Gb/s over 76 km without either the EDFA or the external probe laser, both of which are traditionally re- quired. Additionally, device characteristics such as data-rate transparency, input dynamic range, amplified gain, and 2R regen- eration performance are investigated experimentally. Index Terms—Fabry-Perot (FP), reamplification and reshaping (2R) regeneration.
