Polymer-Optical-Fiber Lasers and Amplifiers Doped with Organic Dyes

Abstract

Polymer optical fibers (POFs) doped with organic dyes can be used to make efficient lasers and amplifiers due to the high gains achievable in short distances. This paper analyzes the peculiarities of light amplification in POFs through some experimental data and a computational model capable of carrying out both power and spectral analyses. We investigate the emission spectral shifts and widths and on the optimum signal wavelength and pump power as functions of the fiber length, the fiber numerical aperture and the radial distribution of the dopant. Analyses for both step-index and graded-index POFs have been done.

Luminescent Properties of Oxazine 170 Perchlorate Doped PMMA Fiber

“…In such case, the excitation pump radiation wavelength can be shifted into the 525 nm transmission window observed in the step index profile of PMMA fiber [28] where Nd:YAG, the second harmonic wavelength (532 nm) laser radiation can be used. In fact, the high quantum yield of organic laser dyes allows efficient light amplification on the short distances (tenths of cm) in comparison with lanthanide ions doped silica amplifiers (tenths of m) [31]. Moreover, the big core diameter and high optical aperture of PMMA fluorinated cladding fibers allow effective coupling of optical radiation with co-working electronic devices (light sources and detectors).…”

“…The incorporation of luminescent dopants in polymeric optical fibers gives the opportunity to new construction development and exhibits new applications fields in optical fiber technology. Among the numerous applications, the most important are light sources, amplifiers, and sensors [31,32]. Polymeric chain structure allows directing incorporation of luminescent complexes or guest-host doping mechanism.…”

Polimerozko zuntz optiko dopatuen erabilera laser eta anplifikagailu gisa

“…Fotoi-igorpenetan trantsizioak S 2 -ren beheko azpimailatik S 1 -era gertatzen dira, eta fotoi-xurgapenetan alderantziz; hau da, S 1 -en beheko azpi-mailatik S 2 -ra. Ondorioz, dopaturiko zuntzen ezaugarri optikoak bi energia-mailen arteko denboraren menpeko tasa-ekuazioen bitartez aztertzen dira normalean [7]. Zehatzagoak izateko, determinatu beharreko funtzio ezezagunak honako hauek dira: P(t, z, λ) (denbora, posizioa eta uhin-luzeraren menpeko argi-potentzia) eta N 2 (t, z) (denbora eta posizioaren menpeko populazio elektronikoa, kitzikaturiko egoeran).…”

Energy conversion in 7-(Diethylamino)coumarin doped PMMA fluorescent fibre

“…The step/gradient index and microstructured optical fibers can be fabricated using PMMA host (Miluski et al 2016b;Tama et al 2010;Bundalo et al 2014;Kailasnatha et al 2008;Oliveira et al 2015;Huang et al 2004;Barton et al 2004). Moreover, the guiding properties of optical fibres can be used to obtain some specific advantages: optical signal amplification, amplified spontaneous emission (ASE), and energy transfer (Karimi et al 2004;Dorosz et al 2012;Arrue et al 2011;Ayesta et al 2011;Nihei et al 1996). The optical amplifiers, sensors, and lasers based on fluorescent organic complexes were reported so far (Dorosz et al 2012;Arrue et al 2011;Ayesta et al 2011;Nihei et al 1996).…”

The Stoke shift, mirror symmetry of absorption and emission spectra, high quantum yield and short lifetime (few ns) were reported in PMMA host doped by coumarins (Johansson 1991;Al-Hamdani et al 2010;Kailasnatha et al 2008).…”
