High silica dispersive optical fiber and its application as an in-line short pass fiber filter

Summary form only given. In this study, a dispersive fiber based on a high silica glass host is fabricated for the first time. The dispersive characteristics of the index difference was achieved using the index variation of SiO/sub 2/-B/sub 2/O/sub 3/ and SiO/sub 2/-F glass. To make a short-pass filter, the core and cladding compositions were chosen as SiO/sub 2/-B/sub 2/O/sub 3/ and SiO/sub 2/-F respectively.
