PROBLEM TO BE SOLVED: To provide a very thin and compact optical fiber sheet to be applied to an optical fiber amplifier, etc., and capable of controlling the variation of wavelength characteristic relative to the temperature change of an optical fiber having temperature dependence. SOLUTION: The optical fiber sheet (1) characterized in that an optical fiber 2 is laid on a substrate (3) having a temperature adjusting function by conducting power. A temperature sensor (16), a fiber temperature adjusting circuit (14) and conducting electrodes (8), etc., can be provided on the substrate (3). COPYRIGHT: (C)2003,JPO |
