Abstract
An optical amplifying medium has an optical amplifying medium for amplifying signal light, a first substrate on which the optical amplifying medium (e.g., erbium-doped optical fiber) is placed, a second substrate opposite to the fist substrate to sandwich the optical amplifying medium between the fist substrate and the second substrate, and a first temperature control element for controlling the temperature of the fist element, for amplifying light beams of several different wavelengths together to be applied in wavelength-multiplexing transmission so that it provides a property of stable optical amplification and it is prevented from occurring variations in the wavelength characteristics of gain in spite of occurring variations in surrounding temperature.
