Abstract |
By incorporating a polarization-diversity loop configuration (PDLC), we have demonstrated inline conversion between transmission and reflection spectra of a fiber Bragg grating (FBG) without reconfiguration of the fiber filter structure. The proposed apparatus consists of a polarization beam splitter, an FBG, and two quarter-wave plates (QWP"s). The inline conversion operation between transmission and reflection spectra of the FBG was performed by proper adjustment of QWP"s within the proposed filter. The band rejection ratio and side-mode suppression ratio in transmission and reflection modes of the fabricated filter were measured as ∼17.0[㏈] and ∼16.4[㏈], respectively. |
