Abstract
An optical direct amplifier lowers the power consumption with a simple structure at a low cost. This amplifier includes an optical amplification medium (e.g., optical fiber) that carries out an optical amplification function in response to optical excitation by an exciting light source (e.g., semiconductor laser); a temperature controller for controlling the temperature of the amplification medium; a heat radiating member for radiating the heat generated by the light source; and a heat transmission regulator (e.g., Peltier module) for allowing the heat to flow into the amplification medium from the light source and for preventing the heat from flowing into the light source from the amplification medium. The amplification medium is heated by application of the heat generated by the light source by way of the heat radiating member and the heat transmission regulator.
