Abstract: An optical filter is produced that has a desired spectral response. This is done by first decomposing the desired spectral response into individual simulated responses (F1 . . . F4) using a suitable computer program. Then tapered fiber filters are manufactured with parameters that closely match the individual responses. And finally the tapered fiber filters are concatenated on a single-mode fiber to produce the optical filter with a total response that closely matches the desired spectral response.
