Ir Emission

In Er3+/Yb3+codoped Na2O-ZnO-PbO-GeO2-TeO2(NZPGT) glasses, effective ~1.5mm infrared (IR) emission was investigated under 980nm excitation. Judd-Ofelt intensity parameters Wt (t = 2, 4, 6) had been calculated to be 6.78´10-20, 1.54´10-20, and 1.17´10-20cm2,respectively. The IR emission full width at half maximum (FWHM) is 73nm, and the maximum stimulated emission cross-section (se) is derived to be 7.53×10-21cm2. A figure of merit (FOM) as the product FWHM´se is adopted to evaluate the gain bandwidth. The comparison of FOM in different glasses indicated that Er3+/Yb3+codoped NZPGT glasses were potential materials in developing broadband optical amplifier.

Spectroscopic properties in Er3+-doped Ga2O3-GeO2-Bi2O3-PbO（BP）glass have been investigated and their promising application as Er3+-doped fiber amplifiers (EDFA) has also been evaluated under the excitation of 980 nm. The important roles of Bi2O3 substitution for PbO on spectroscopic properties, such as Judd-Ofelt intensity parameters (t=2, 4, 6) and emission spectra of Er3+, have been studied. The calculated peak emission cross-section of the 4I13/2→4I15/2 transition of Er3+ ions are 16.03×10-21 cm2 when the substituted PbO content by Bi2O3 is about 25 mol. The product of the peak emission cross-section ( ) and the full width at half-maximum (FWHM) of the sample is~689.29×10-28 cm3, which is higher than that of Er3+-doped silicate, phosphate and ZBLAN glasses. It was found that the substitution of Bi2O3 for PbO provides two potentials: broadening the full width at half-maximum of 1.53 μm fluorescence and improving the values of FWHM× of Er3+. The results strongly support that the Er3+-doped BP2 glass could be identified as a promising material for achieving 1.53 μm fiber amplifier.

Abstract: Zinc lithium lead calcium borophosphate glasses containing Er3+ in (40- x):P2O5:10ZnO:10Li2O:10PbO:10CaO:20B2O3:xEr2O3 (where x=1, 1.5,2 mol %) have been prepared by melt-quenching method. The amorphous nature of the glasses was confirmed by x-ray diffraction studies. Optical absorption, Excitation, fluorescence and Transmittance spectra were recorded at room temperature for all glass samples. Judd-Ofelt intensity parameters Ωλ (λ=2, 4, 6) are evaluated from the intensities of various absorption bands of optical absorption spectra. Using these intensity parameters various radiative properties like spontaneous emission probability, branching ratio, radiative life time and stimulated emission cross–section of various emission lines have been evaluated.

Optical signal amplification in the waveguiding structure of optical fibers can be used for optical telecommunication systems and new light sources constructions. Organic dyes doped materials are interesting for new applications in polymeric optical fibers technology due to their benefits (efficient fluorescence, high absorption cross section, and easy processing). This article presents a numerical simulation of gain in poly(methyl methacrylate) optical fiber doped by Oxazine 170 Perchlorate. The calculated gain characteristic for the used dye molar concentration (0.2·10-6–1.4·10-6) and pump power (1–10 kW) is presented. The fabricated fluorescent polymeric optical fiber is also shown. The presented analysis can be used for optical amplifier construction based on dye-doped polymeric optical fiber (POF).

Glasses of the system: xB2O3-10Bi2O3-30Li2O-xPr6O11 where x =1, 1.5 and 2 were prepared by melt quenching technique. Optical absorption and emission spectra have been recorded. The intensities of f-f transition are calculated in term of Judd-Ofelt (JO) intensity parameters Ωλ (λ = 2, 4 and 6). Using the fluorescence data and these Ωλ parameters, various radiative properties like transition probability (Arad), branching ratio (βR), radiative lifetime (τR), and stimulated emission cross section (σp), of various emission lines have been evaluated. The branching ratio for 3P0→3H4 transition is 56% and the predicted spontaneous radiative transition probability rates are fairly high 16411 s−1. This is beneficial for lasing emission.

Wavelength Division

The incorporation of cascaded and hybrid-type optical amplifiers into the optical fiber link is advantageous for the purpose of achieving wide gain bandwidth of multi-wavelength coarse wavelength division multiplexing (CWDM) systems. Different amplifiers whose operating gain region differ from each other are connected in cascade, thus providing better gain performance as the overall gain is combined and flattened over a larger spectrum. In this paper, the effect of the crossover of the uniform gain of the semiconductor optical amplifier (SOA) and the nonuniform gain of erbium-doped fiber amplifier (EDFA) is analyzed using an in-line cascaded SOA-SOA and an in-line hybrid SOA-EDFA configuration in the amplification of an 8-channels CWDM system obtained from the simulation using Optisystem software. It was observed that the cascaded SOA-SOA produces higher gain of 25 dB and wider gain bandwidth of 60 nm compared to the hybrid SOA-EDFA configuration with maximum gain of only 24 dB and 40 nm bandwidth. In addition, better bit-error-rate (BER) performance which is within the typical values in optical fiber communication is also achieved from the cascaded SOA topology. Wider gain bandwidth obtained with the SOA-SOA configuration would permit the transmission of video application at 1551 nm in the proposed Ethernet CWDM system transmitted at 100 Mb/s data rates.

Dy3+ doped alumino borotellurite (ABT) glasses xB2O3+(80-x)TeO2+10Al2O3+10CaO+ 0.5Dy2O3 (where x = 35; 45 and 55) have been prepared by melting method. Their optical properties were studied through absorption, luminescence spectra and decay time measurements. Judd-Ofelt (JO) intensity parameters (Ωλ, λ = 2, 4 and 6) have been determined using absorption spectra and are been used to calculate the radiative parameters like transition probability, stimulated emission cross-section, branching ratios, gain band width and optical gain for the 4F9/2→6H13/2 transition in Dy3+ ions. The chromaticity coordinates is used to estimate the emission feature of prepared glasses.
