Fresnel Reflection Spectra at Multimode Optical Fiber Ends with Heterodyne Detection

- 論文の詳細を見る
The Fresnel reflection (FR) spectra at the ends of a step-index (SI-) multimode fiber (MMF) and a graded-index (GI-) MMF were investigated with heterodyne detection, and compared with that of a standard single-mode fiber (SMF). The FR spectra of the MMFs were found to spread broader than that of the SMF, and the FR spectrum of the SI-MMF was even broader than that of the GI-MMF. It was also demonstrated that the observation of the Brillouin gain spectrum in a polymer optical fiber (POF) is severely influenced by the FR spectrum. We believe that this information will provide a guideline for the design of robust Brillouin sensing systems using MMFs including POFs.
