An Efficient Photonic Crystal Fiber-Based Brillouin Erbium Fiber Laser Using a Fiber Bragg Grating for Multi-Wavelength Generation

Abstract

An efficient multi-wavelength Brillouin erbium fiber laser is demonstrated using an improved configuration with a broadband fiber Bragg grating and a piece of photonic crystal fiber. The laser generates more than 55 lines of optical comb with a line spacing of approximately 0.09 nm in a 1,565-5 nm region using pump powers of 3 dBm and 150 mW for the Brillouin and 980-nm pumps, respectively. The Brillouin erbium fiber laser with a fiber Bragg grating's reflectivity of 50% obtained a higher number of comb lines compared to that of 99% reflectivity.

Multiwavelength Brillouinerbium fiber lasers were also demonstrated: using a 70 m solid-core highly nonlinear PCF [86,87] or by using 100 m PCF [88]. Ytterbium-doped fiber lasers were developed: pumping a highly nonlinear PCF with zero-dispersion [89], or using a 20 m PCF to provide four-wave mixing [90], or through a polarization maintaining PCF for dispersion compensation [91], or even with an anomalous dispersion PCF [92].…”
