【正文】 urn to the singlet ground state molecules that fluoresce. Refractive index distribution by fluorescence of structure POF can be divided into fluorescent SI POF and fluorescence GI POF, doped organic dye POFA most important feature is the wide range of wavelengths to provide high power output. Fluorescent POF schematic diagram of the transmission of light below, it meets the general fiber of the transmission SI optical properties, but different from the wavelength of incident light wavelength of light emitted. Fluorescent light POF there is another way of transmission, which is irradiated from the side of the incident light can be fluorescent POF, the output beam emitted from the fiber surface at both ends, of course, the wavelength of incident light is different from the transmission wavelength of light emitted. Optical properties of fluorescent material mainly depends on the matrix material, the same fluorescence characteristics of POF gain amplification pump wavelength, fluorescence POF length and the amount of dopant and concentration. Gain G is called POF output signal power Pout to the input optical power ratio between a Pin.4. Conclusion POF can be passed just because of the fiber with the core structure of the skin, the light transmission of POF is based on principle of total reflection of light transmission, light transmission in the SI POF in the zigzag way for the total reflection type of light in the GI POF in the transmission mode is the sine curve type。 the same time to simplify the calculation, the parameters used for calculation of Meridian, Meridian is the propagation path of light through the optical axis and is always in the same plane, the calculation of these parameters include the maximum angle of incidence or emission angle, numerical aperture, In the steptype fiber radial geometry and reflection travel times。 side light and fluorescence POF POF is by total internal reflection of light transmission principle, for more than singlecore POF side light loss caused by the side of nonnatural light, and for multicore side of the light bending loss POF is produced by the luminous side. After a specific wavelength of fluorescence excitation POF issued after a specific wavelength of light, and not only exciting light incident from the end, but also from the side of the ncident.
