“…The experimental results show that the proposed router has quite similar values of IL in both outputs (OFF and ON states) in the range from 400-nm, as well as CT values lower than À18.68 dB. This performance is required for routing channels in SI-POF-WDM networks uniformly [1,2], since in these networks the channels have wide bandwidths (LED sources are often used) and the proposed grid is very wide [3,[6][7][8]. The router improvement has been done without complicating its construction and using commercially available LC cells (fixed thicknesses).…”

“…Today, POF is displacing copper step by step, especially in the automotive industry, because it saves more space and weight and offers immunity to electromagnetic interferences. POFs are also a low cost solution for the development of shortrange high-speed data networks, as in home and office networks, for the ease of making connections since they have higher dimensions, larger numerical aperture and larger critical curvature radius, in comparison with glass optical fibers, which allows the necessary curvatures in the wiring of home networks [1]. Moreover, it has been shown that POFs have multiple applications in sensor systems at low or competitive cost compared to the wellestablished conventional technologies [2].…”

A1Â 2 optical router based on an achromatic liquid crystal polarization rotator has been designed and experimentally tested. The router can work in the spectral range used in stepindex polymer optical fiber networks (400-700 nm) with low wavelength and temperature dependences. The theoretical design is fast and simple and has good agreement with experimental results. Experimental crosstalk is lower than À18.68 dB for both outputs, even with thermal variations of 10 1C. Performance improvement with respect to previously reported devices with similar structure has also been analyzed.

“…The lowest attenuation (c.a. 40 dB/km) is observed for window 525 nm [28]. Significantly higher attenuation in the red part of VIS and IR range comes from the absorption of carbon-hydrogen overtone bond vibration.…”

“…The high PMMA absorption of excitation radiation can be overcome by using shorter wavelength excitation since the pump radiation affecting length can be significantly longer than in bulk samples. 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].…”

Abstract:The article presents fabrication and luminescent properties of poly(methyl methacrylate) (PMMA) fiber doped by Oxazine 170 perchlorate. The bright fluorescence of polymeric fiber (at molar fluorescent organic dye concentration 4.3 × 10 −5 ) was characterized in terms of spectrum and signal attenuation vs. the fiber length. The significant changes in fluorescence spectrum (λ max red shift average slope 4.6 nm/cm and Full Width at Half Maximum (FWHM) increasing slope 6.7 nm/cm) have been noticed for the length of the fiber (0.02-0.08 m) which corresponds to a high overlapping region of absorption and emission spectra of used dye. The red shift of λ max (c.a. 80 nm) was presented in fabricated polymeric fiber at distance 0.85 m. The obtained characteristics can be used for luminescent properties optimization of fluorescent organic-dye-doped PMMA fiber.

“…Optical transmission can be easily obtained for PMMA attenuation optical windows of 465, 525, 565, and 650 nm. The lowest attenuation of the PMMA core POF is approximately 100 dB/km [16][17][18]. Much higher losses are observed for the infrared radiation spectrum.…”

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).
