<p><P>PROBLEM TO BE SOLVED: To provide a fiber type narrow-band wavelength selective filter which has a low loss, can selectively transmit a plurality of narrow-band signals and has high design flexibility. <P>SOLUTION: The fiber type narrow-band wavelength selective filter is provided with: a fiber type Fabry-Perot etalon which selectively transmits the plurality of narrow-band signals; and a fiber grating which selectively intercepts an unnecessary signal among signals selected by the fiber type Fabry-Perot etalon. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
