Fluorescent fibers are optical fibers which emit light as a response to an incident phenomenon, usually an incident light. Operation depends on the doping dyes, which determine specific fluorescence and optical characteristics useful in the development of optical sensors. In this work we propose a low-cost distributed proximity sensor implemented using a red fluorescent fiber, to provide a security option for a surface plasmon resonance system. Operation of the proposed sensor relies on having the incident illumination intensity varied by the presence or absence of an obstacle in the vicinity of the sensing element. This will influence the radiated fluorescence accordingly. The proposed setup for the implementation of the optical proximity sensor assumes having a high brightness LED deployed for axial fiber illumination and a blue LED for side illumination. Electronic processing then accounts for gain and digitization. Measurement results of the prototype validate the proposed concept.

“…There is a lack of understanding the behavior of two dyes in the same silica environment where excited-state energy transfer process might occur. However, donor and acceptor pairs of fluorescent dyes have been loaded in silica sol-gel to produce solid-state dye lasers with increased laser efficiency and tunable spectral range [21][22][23]. By using micrometer size silica spheres with donor and acceptor dyes, there may be a possibility to form a whispering gallery dye laser with energy transfer.…”

The laser performance of coumarin 440 (C440) and coumarin 460 (C460) mixture is studied. The mixture dyes demonstrated broader and more efficient tuning curves compared with those of coumarin 440 and coumarin 460. A wide tuning range from 421 nm to 482 nm is achieved. The highest conversion efficiency of 12.2% is obtained at 453 nm. Comparing with the efficiencies of individual dye C440 and C460, which are ∼5%, the tuning range and the conversion efficiency of the coumarin 440 (C440) and coumarin 460 (C460) mixture are the best under the same condition so far. All our results indicate that high laser performance can be achieved using the co-doped laser dyes of coumarin 440 and coumarin 460.
