Investigation of Brillouin effects in small-core holey optical fiber: lasing and scattering
We demonstrate for what is believed to be the first time a Brillouin laser based on a holey fiber (HF). Using a simple Fabry-Perot resonator scheme containing a 73.5m long highly nonlinear HF with an effective area of 2.85µm2, we obtain a threshold of 125mW and a slope efficiency of ~70%. Stimulated and spontaneous Brillouin scattering effects are investigated in the HF, and we show that the high lasing threshold is due mainly to reduction of the effective gain coefficient caused by structural nonuniformity along the fiber length.

Abstract

We demonstrate for what is believed to be the first time a Brillouin laser based on a holey fiber (HF). Using a simple Fabry-Perot resonator scheme containing a 73.5m long highly nonlinear HF with an effective area of 2.85µm2, we obtain a threshold of 125mW and a slope efficiency of ~70%. Stimulated and spontaneous Brillouin scattering effects are investigated in the HF, and we show that the high lasing threshold is due mainly to reduction of the effective gain coefficient caused by structural nonuniformity along the fiber length.
