This hence eliminated the need for optical filters and minimized the effects of intensity fluctuations. The computation of these components for two specified wavelengths (peak excitation and emission) produced a dimensionless ratiometric relationship for varying concentrations of fluorescence dye. This was followed by the calculation of absorption and fluorescence emission at each point of reflection, which were subsequently summed and averaged over all the launched rays. It involved the plotting of ray trajectories confined by total internal reflection within a geometrically simplified PCF core. We report a simplified model for the computation of light-fluorescence interactions within photonic crystal fibers (PCFs).

Note: Author names will be searched in the keywords field, also, but that may find papers where the person is mentioned, rather than papers they authored.Use a comma to separate multiple people: J Smith, RL Jones, Macarthur.Use these formats for best results: Smith or J Smith.For best results, use the separate Authors field to search for author names.Use quotation marks ' ' around specific phrases where you want the entire phrase only.Question mark (?) - Example: 'gr?y' retrieves documents containing 'grey' or 'gray'.Asterisk ( * ) - Example: 'elect*' retrieves documents containing 'electron,' 'electronic,' and 'electricity'.Improve efficiency in your search by using wildcards.Example: (photons AND downconversion) - pump.

Example: (diode OR solid-state) AND laser.

Note the Boolean sign must be in upper-case.

Separate search groups with parentheses and Booleans.

Keep it simple - don't use too many different parameters.
