Abstract(in Japanese) (See Japanese page)
Abstract(in English) Gain distribution along Er-doped optical fiber amplifiers (EDFA) was measured by means of coherent OFDR. An external cavity DFB laser emitting at 1.55 μm was used as a light source, and it optical frequency was swept by changing the external cavity length. The Rayleigh backscattering in the EDFA could be detected by suppressing Fresnel reflection at the far end of the EDFA, and as a result, the gain distribution along the EDFA was estimated. The input-output gain of the EDFA measured by the coherent OFDR agreed well with the gain measured by an optical spectrum analyzer.
