POLARIZATION INDEPENDENT OPTICAL AMPLIFIER APPARATUS |
| 摘要 |
POLARIZATION INDEPENDENT OPTICAL AMPLIFIER APPARATUS A polarization independent semiconductor amplifier is used in a double-pass configuration; that is, the output of the amplifier is passed through a 45.degree. Faraday rotator to a mirror and then through the rotator and the amplifier again. Polarization independent gain is thus achieved. |
