Abstract

The performance of a high output power Erbium Ytterbium doped fiber amplifier (EYDFA) and Erbium ytterbium doped fiber laser are investigated using a star shape double clad fiber in conjunction with 927 nm cladding pumping. The EYDFA provides a flat gain of 22.4 dB within a wavelength region ranging from 1545 nm to 1570 nm when the input signal and pump powers are fixed at 0 dBm and 3 W, respectively. The corresponding noise figure is 5.73 dB at 1550.4 nm. A broadband fiber Bragg grating (FBG) is used in conjunction with a perpendicularly cleaved output fiber to achieve lasing at 1565.5 nm with a threshold pump power of as low as 0.1 mW. The output power of 1060 mW is achieved with pump power of 2.8 W, which translates of 39% efficiency without any sign of roll over..
