Abstract
A bidirectional optical amplification system which includes an optical amplifier having an input and an output and configured to amplify wavelengths lying within a range of wavelengths and an optical coupling device. The optical coupling device includes a first port configured to receive a first optical wave in a first subrange of wavelengths lying within a range of wavelengths, a second port configured to receive a second optical wave in a second subrange of wavelengths lying within the range of wavelengths, an optical coupling output coupled to the input of the optical amplifier, and an optical coupling input coupled to the output of the optical amplifier. The optical coupling device directs the first optical wave from the first port to the optical coupling output, directs an amplified optical wave, resulting from amplification of the first optical wave, from the optical coupling input to the second port, directs the second optical wave from the second port to the optical coupling output, and directs an amplified optical wave, resulting from amplification of the second optical wave, from the optical coupling input to the first port.
