Abstract:
In this paper, an indium antimonide (InSb) saturable absorber (SA) was
successfully fabricated. The saturable absorption properties of the InSb SA were studied, and they show a modulation depth and a saturable
intensity of 5.17% and 9.23MW/cm 2 , respectively. By employing the InSb
SA and building the ring cavity laser structure, the bright–dark soliton operations were successfully obtained by increasing the pump
power to 100.4 mW and adjusting the polarization controller. As the pump power increased from 100.4 to 180.3 mW, the average
output power increased from 4.69 to 9.42 mW, the corresponding fundamental repetition rate was 2.85 MHz, and the
signal-to-noise ratio was 68 dB. The experimental results show that InSb with excellent saturable absorption characteristics can be
used as a SA to obtain pulse lasers. Therefore, InSb has important potential in fiber laser generation, further applications in
optoelectronics, laser distance ranging, and optical fiber communication, and it can be widely developed.
