Analysis of S-band EDFA utilising macro-bending approach

International Conference On Photonics 2010, 2010

Positive gain is obtained in 1460 to 1520 nm region of single pass configuration erbium doped fiber amplifier (EDFA) using macro-bending approach. The standard step index EDF is bent on a 0.65 cm radius rod to suppress the ASE at the longer wavelength in order to achieve the amplification in shorter wavelength region. The bent EDF shows gain and noise ...


Effect of stimulated Brillouin scattering on distributed erbium-doped fiber amplifier

IEEE Photonics Technology Letters, 1993

Stimulated Brillouin scattering (SBS) causes backward scattering of the pump light and this in turn causes a reduction in the gain of a distributed erbium- doped fiber amplifier (DEDFA). A theoretical analysis of the influence of SBS on a DEDFA and illustrative numerical results are presented. It is shown that there exists a threshold value of pump laser linewidth: when ...

  • Analysis of S-band EDFA utilising macro-bending approach

    Positive gain is obtained in 1460 to 1520 nm region of single pass configuration erbium doped fiber amplifier (EDFA) using macro-bending approach. The standard step index EDF is bent on a 0.65 cm radius rod to suppress the ASE at the longer wavelength in order to achieve the amplification in shorter wavelength region. The bent EDF shows gain and noise figure improvement than that of unbent EDF. The effect of multiple EDF lengths on gain and noise figure across S-band region is also studied.

  • Effect of stimulated Brillouin scattering on distributed erbium-doped fiber amplifier

    Stimulated Brillouin scattering (SBS) causes backward scattering of the pump light and this in turn causes a reduction in the gain of a distributed erbium- doped fiber amplifier (DEDFA). A theoretical analysis of the influence of SBS on a DEDFA and illustrative numerical results are presented. It is shown that there exists a threshold value of pump laser linewidth: when the pump laser linewidth is smaller than this threshold value the gain of the DEDFA is reduced greatly. This analysis and the results presented facilitate the design and optimization of DEDFAs.<<ETX>>

  • 30dBm Wideband Air-Clad EDFA Using Two Pump Lasers

    The performance of a 30dBm erbium amplifier using air-clad fibre and only two 980nm pumps is reported. The amplifier is characterized by a low noise figure and low gain ripple over the entire C band.

  • A Mueller matrix formalism for modeling polarization effects in erbium-doped fiber

    The effects of erbium anisotropy in erbium-doped fiber lasers, sources, and amplifiers are examined. Starting from basic ion properties, inversion and gain equations are derived analytically to describe polarization dependencies. A novel matrix form of the Er/sup 3+/ rate equations is presented to propagate powers and polarization states. These equations are then numerically integrated and compared to experimentally observed polarization hole burning and polarization dependent gain. The theoretical predictions agree strongly with experiment in all cases.

  • Wavelength tunable CW Raman fiber ring laser operating at 1486-1551 nm

    Summary form only given. Erbium doped fiber lasers and amplifiers have provided a wealth of high power sources in the 1530 to 1580 nm spectral region. Other dopants such at ytterbium and thulium offer gain in other limited spectral regions but the non-linear effect of stimulated Raman scattering (SRS) provides for gain at any wavelength with the provision of a suitable pump source. Here we detail the optimization of a tunable fiber Raman ring laser with CW output between 1486 and 1551 nm, and use it to provide Raman gain over a tunable wavelength range of 1589 to 1650 nm.

  • Adiabatic soliton compression from 8 ps to 120 fs in a cascaded Raman/erbium fiber amplifier

    Summary form only given. Pulse compression is a well-known technique to obtain short pulse duration and broad spectrum. Adiabatic soliton compression (ASC) is highly sensitive to the noise of input pulses but has been shown to be efficient and robust against noise. Here we report the first ASC in a cascaded Raman/erbium fiber amplifier in which 8-ps pulses from a dispersion- compensated DFB laser were simultaneously compressed and amplified by over 60-fold.

  • The status of fiber optics

    This paper gives a general review of the historical development and current status of the fiber optic industry. It encompasses such technical topics as erbium doped fiber amplifiers (EDFA), semiconductor lasers, dense wavelength division multiplexed (DWDM) systems, fiber networks, LiNbO based modulators, and dispersion compensation. In addition, it discussed the economic infrastructure of the fiber optics industry and the role played by basic materials and device development.
