167 W, power scalable ytterbium-doped photonic bandgap fiber amplifier at 1178 nm.
An ytterbium-doped photonic bandgap fiber amplifier operating at the long wavelength edge of the ytterbium gain band is investigated for high power amplification. The spectral filtering effect of the photonic bandgap efficiently suppresses amplified spontaneous emission at the conventional ytterbium gain wavelengths and thus enables high power amplification at 1178 nm. A record output power of ...
متن کاملComparative Gain Analysis of Erbium and Ytterbium Doped Optical Fibre Amplifiers
In the present work, gain of EDFA (Erbium Doped Fibre Amplifier) and YDFA (Ytterbium Doped Fibre Amplifier) are analyzed based on their performance parameters. The effects of pump laser power, length of doped fibre that used for amplification and the wavelength of the input signal on the gains of the optical amplifiers is examined. EDFA exhibits maximum gain of 48db around 1550nm regions with p...
متن کاملThermoluminescence Response of Ytterbium-doped and Undoped of Silicon Optical Fiber Subjected to Photon Irradiation
Radiation effects of photon irradiation in Ytterbium-doped silica optical fibers are still much less explored despite their importance in space-based application as radiation dosimetry. This study investigates and compares the thermoluminescence glow curve, response, linearity and sensitivity of Ytterbium-doped SiO2 optical fibers with that of TLD-100. Samples are placed in solid phantom and ir...
متن کاملSimultaneous effects of photo- and radio- darkening in ytterbium-doped aluminosilicate fibers
We present original characterizations of photo-radio-darkening in ytterbium-doped silica optical fibers submitted to the simultaneous action of the pump and of an ionizing radiation. We present the interplay between both radiations, showing e.g. that the pump is able to darken or bleach the fiber depending on the ionizing dose. The photoresistance of the fiber is shown to play a crucial role on...
متن کاملTunable multiwavelength fiber laser using a comb filter based on erbium-ytterbium co-doped polarization maintaining fiber loop mirror.
A tunable comb filter based on a fiber loop mirror setup, which incorporates a piece of pumped erbium-ytterbium co-doped polarization maintaining fiber, is newly presented. It is accomplished by controlling the pump power or adjusting a polarization controller in the loop mirror, which results from the fact that the effective birefringence of the erbium-ytterbium co-doped polarization maintaini...
