  • Optimization of Fusion Splice Process for High Numerical Aperture Coupler Fiber and Erbium Doped Fiber (.pdf)
    Fusion splicing erbium doped fiber (EDF) to other single mode fibers has become more critical as the required overall insertion loss for erbium doped fiber amplifiers (EDFA) has significantly decreased in the last few years. In this paper, we describe and discuss an approach to developing a low
  • Increased Pulsed Amplifier Efficiency by Manipulating the Fiber Dopant Distribution (.pdf)
    Cladding pumped fiber lasers and amplifiers have emerged as a competing technology for solid state lasers. In order to obtain high powers and mitigate nonlinear effects large mode area (LMA) rare-earth doped fibers have been used [1-3]. In LMA fibers, the area of the fundamental mode of the fiber
  • Advanced Topics on Erbium Doped Fibers for High Performance Amplifiers (.pdf)
    Erbium doped fiber amplifiers have been widely deployed for signal amplification in optical transmission systems. High performance amplifiers require erbium doped fiber with high power conversion efficiency and consistent flat gain spectrum. In addition, all impairments associated with EDF must
  • New Fiber-optic Amplifier for DIN-rail Mounting, Series 3060
    Photoelectric devices for DIN-rail mounting (picture 1) are used exclusively in fiber-optic applications. The idea is to build the devices into already available switchboxes or housings, together with other electromechanical and electronic components. Since these components are today normally
  • Bending Induced PMD in Spun Erbium Doped Fiber (.pdf)
    With a growing number of systems running at 10 Gbit/s and large interest in 40 Gbit/s systems, there is increased focus on Polarization Mode Dispersion (PMD). Even though EDF amplifiers only consist of tens of meters of EDF, the PMD tolerance on the fiber is tight. But measuring the correct PMD
  • Supercontinuum Generation in SCG-800 Photonic Crystal Fiber
    include the following: white light (supercontinuum) seeded Optical Parametric Amplifiers (, transient absorption spectrometers ( among others, all requiring amplified ultrafast systems. In recent years, renewed interest in supercontinuum generation has been
  • Semiconductor Optical Amplifier in Coarse Wavelength Division Multiplexed Systems
    Coarse division wavelength multiplexed (CWDM) systems have been proposed for reducing the cost of metro and access networks while providing increased throughput and flexibility. CWDM multiplexes up to 16 wavelengths on a single fiber using ITU standard (G.694.2) 20 nm spacing between
