Abstract

In this paper, the development of multi-wavelength Brillouin fiber laser with fiber Bragg grating utilizing a loop mirror is successfully demonstrated. A multi-wavelength Brillouin fiber laser configuration employs 11 km length of single mode fiber as the gain medium, while the reflection of fiber Bragg grating is adopted to produce multi-wavelength signals. Based on the experimental results, it shows that the position of the fiber Bragg grating in the Brillouin fiber laser configuration plays an important role in producing the multi-wavelength signals. By using 19.0 dBm of Brillouin pump power, the highest number of Brillouin Stokes signal and tuning range obtained from this formation is about 23 and 4 nm, respectively. Furthermore, 50% output coupling ratio demonstrates the best ratio to produce Brillouin Stokes signal which gives a better performance in the Brillouin fiber laser system.

Summary

Introduction

The growth towards the communication is rapidly increasing with the higher demands on the data bandwidth which led to the development of the optical fiber and the exploration on the long haul transmission media [1,2,3,4,5,6]. The SBS is a nonlinear process in optical fiber which involves the interaction between intense pump light and acoustic wave [13] This process produces a unique result where Brillouin Stokes (BS) signals are generated in backward propagation at a downshifted frequency of ~ 0.08 nm (10 GHz) from the injected signal wavelength [13]. The implementation of the fiber Bragg grating (FBG) and loop mirror in the BFL configuration plays an important role in generating the multi-wavelength signal This FBG is known as the optical fiber core that possess a special disorder refractive index region which it will diffracts the light ray propagation at a particular wavelength [14]. At 50% output coupling ratio and 19.0 dBm of BP power, 23 BS signals are produced This configuration has been operated in the C-band region in the range of 1530 nm to 1565 nm transmission wavelength. This band promotes the lowest attenuation and compatible system with amplifiers [16]
