OPTICAL CLEAN-UP FILTERS AND METHOD OF MAKING THE SAME

摘要

An optical clean-up filter is produced that has a desired spectral response. This is done by first decomposing the desired spectral response into individual simulated responses 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 clean-up filter with a total response that closely matches the desired spectral response.
