All-optical regeneration using a side-mode injection-locked semiconductor laser

摘要

We propose and demonstrate all-optical regenerations using a side-mode injection-locked or a two-side-mode injection-locked semiconductor laser. We found that these techniques can decrease the effect of relaxation oscillation both in simulation and experiment. By using a two-side mode-injection-locked semiconductor laser, we could regenerate a 5 Gb/s signal distorted by the chromatic dispersion of a 20-km-long standard single mode fiber.
