Erbium Doped Fiber Amplifier (EDFA) for C-Band Optical Communication System
One distinct feature of an optical fiber is that there is a wide spectral region where signals are transmitted in optical fiber. Since most light sources used in high-capacity optical communication systems emit narrow wavelength or less than 1nm, whilst most full-spectrum fibers for communication application operates in C-band. Thus, the paper reviews the technology of optical amplifier in tele...
متن کاملErbium-Doped Fiber Amplifier Review
This paper is describing and investigating four crucial areas of Erbium Doped Fiber Amplifier (EDFA). First is the atomic part, where it is meaningful to give deep and details information of erbium spectra structure and its energy level. The atomic spectrum is one crucial part in defining and understanding amplification phenomena. The second part based on understanding, investigating and analyz...
متن کاملChirped pulse amplification in an erbium-doped fiber oscillator/ erbium-doped fiber amplifier system OPTICS COMMUNICATIONS
As in bulk amplifiers, the onset of nonlinear effects when amplifying ultra-short pulses in fiber amplifiers has been pointed out and investigated by several groups, specifically in erbium-doped fiber amplifiers ( EDFAs) [ l-3 1. Researchers have in fact used the Kerr nonlinearity in conjunction with group velocity dispersion in order to create even shorter pulses via higher-order soliton forma...
متن کاملObservation of Raman Gain in Reduced Length of Bismuth Erbium Doped Fiber
Raman amplification of a 49 cm Bismuth oxide (Bi2O3) as a nonlinear gainmedium based erbium doped fiber amplifier (EDFA) is reported in new and compactdesign in near infrared spectral regions. The bismuth glass host provides theopportunity to be doped heavily with erbium ions to allow a compact optical gain fiberamplifier design by using reduced fiber length and the 1480...
متن کاملMulti-wavelength Fiber Laser With Erbium Doped Zirconia Fiber and Semiconductor Optical Amplifier
Multi-wavelength hybrid fiber lasers are demonstrated in both ring and linear cavities using a fabricated Erbium-doped Zirconia fiber (EDZF) and semiconductor optical amplifier (SOA) as gain media. In both configurations, the a fiber loop mirror, which is constructed using a 3 m long polarization maintaining fiber (PMF) and a polarization–insensitive 3dB coupler is used as a comb filter for the...
