Abstract
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).
Highlights
Organic electronics have become an alternative for inorganic based devices
Their structural properties allow incorporation directly into polymethyl methacrylate (PMMA) which is commonly used in polymer optical fiber technology
The absorption and emission cross sections of organic dyes are typically significantly higher than those observed in lanthanide ions, which are well known for their narrow absorption bands
Summary
Organic electronics have become an alternative for inorganic based devices. The high quantum efficiency of organic fluorophores is useful in numerous optical applications: sensors, light sources, lasers, and amplifiers [1,2,3,4,5,6,7,8,9,10]. The high quantum yield of fluorescence was reported for laser organic dyes (xanthenes, oxazines, 7-aminocoumarins) [11] Their structural properties allow incorporation directly into polymethyl methacrylate (PMMA) which is commonly used in polymer optical fiber technology. The absorption cross section luminescence efficiency of lanthanides can be improved using organic ligands and energy transfer (antenna effect), the chelate molecules luminescence is quenched by PMMA nonradiative transitions and efficient luminescence can be observed only for triplet state europium (Eu3+) and terbium (Tb3+) complexes [19,20,21,22,23,24,25,26] In such circumstances, organic dyes are frequently used in polymer optical fiber technology. The article presents a theoretical investigation of gain in polymeric optical fibers doped by Oxazine 170
