Early warning failure detection for a lasing semiconductor optical amplifier |
| 摘要 |
Early warning failure detetection is provided for an optical amplifier. The optical amplifier is based on a lasing semiconductor optical amplifier, which generates a ballast laser signal in addition to the amplified optical signal. The ballast laser signal exhibits a wavelength shift before failure and this wavelength shift is used as the basis for an early warning of future failure of the amplifier.
