| 发明名称 | Optical amplifier and optical amplifying apparatus | ||
| 摘要 | An optical amplifier amplifies signal light and includes a pump light source that outputs pump light of a wavelength different from that of the signal light; a combining unit that combines the signal light and the pump light output by the pump light source, to output combined light; an amplifying unit that has non-linear optical media that transmit the combined light to amplify the signal light, the amplifying unit further removing, in the non-linear optical media, idler light generated from the signal light and the pump light, and outputting light that results; and an extraction filter that extracts the signal light from the light output by the amplifying unit. | ||

| 主权项 | 1. An optical amplifier that amplifies signal light, comprising: a pump light source that outputs pump light of a wavelength different from that of the signal light; a combining unit that combines the signal light and the pump light output by the pump light source, to output combined light; an amplifying unit that includes a first non-linear optical medium that transmits the combined light to amplify the signal light,an optical filter that transmits the signal light and the pump light included in the combined light transmitted by the first non-linear optical medium, while removing from the combined light, idler light generated from the signal light and the pump light, anda second non-linear optical medium that transmits the combined light transmitted by the optical filter, to amplify the signal light; and an extraction filter that extracts the signal light from the light output by the amplifying unit. | ||
