A novel mode-locked ring laser based on polarization saturation in a semiconductor optical amplifier
نویسنده
چکیده
Recently, in our group 800 fs optical pulses were generated in a mode-locked ring laser operated by polarization saturation in a semiconductor optical amplifier (SOA). We investigate numerically the generation of sub-picosecond optical pulses in such a configuration, consisting of a SOA and a linear polarizer placed in a ring. Polarization saturation in the SOA takes the role of a saturable absorber in the passive mode-locking mechanism. Our results are well in agreement with experiment.

We demonstrate a novel approach for generating a stable and low polarization-sensitive mode-locked fiber ring laser by using a low-cost Fabry-Perot laser diode (FPLD) as both the intracavity mode-locker and the band-pass filter. The FPLD pulses is seeded into a close-loop semiconductor optical amplifier (SOA) based fiber ring laser for harmonic and rational harmonic mode-locking operation. The ...

Based on self-reproduction theory, harmonic and rational harmonic mode-locked semiconductor optical amplifier (SOA) fiber ring lasers have been numerically investigated, respectively. Harmonic mode locking makes a target of obtaining ultra-short pulse. While in rational harmonic mode locking, it is urgently needed to solve that pulse amplitude becomes uneven with the increase of the order of ra...
