WAVELENGTH SELECTIVE OPTICAL FOCUSING APPARATUS USING OPTICAL FIBER AND OPTICAL MODULE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a wavelength selective optical focusing apparatus using an optical fiber, which has excellent reproducibility in manufacturing and prevents aging, and to provide an optical module using the wavelength selective optical focusing apparatus.

SOLUTION: The wavelength selective optical focusing apparatus of the present invention using an optical fiber comprises: a core for transmitting an optical signal therethrough; and a cladding layer surrounding the core and having a plurality of grooves formed in the outer circumferential surface thereof such that the grooves are changed at a designated rate. The wavelength selective optical focusing apparatus is characterized in that an optical signal having a designated wavelength guided by the core is focused to the outside of the cladding layer by the grooves.
