Abstract
Novel attenuators for use in single-channel applications are disclosed. The attenuators include a crosslinked siloxane copolymer composition, prepared by crosslinking a vinyl-terminated dimethylsiloxane-diphenylsiloxane copolymer with a silane crosslinking agent in the presence of a platinum catalyst. The crosslinked copolymer overlies a portion of a side-polished optical fiber or tapered optical fiber. Optical energy propagating through the fiber can be extracted when the refractive index of the crosslinked material is varied about that of the optical fiber. The attenuators are useful in single-channel applications, such as the ever-popular 1310 nm and 1550 nm wavelengths.
