| 英文摘要 | A semiconductor optical amplifier module comprises: a demultiplexer (4, 135) made of a semiconductor material to separate an optical input signal (1, 101) containing a plurality of wavelength components (λ1-λN) into a plurality of demultiplexed signals (6λ1-6λN), each of the demultiplexed signals having a different one of the wavelength component; a plurality of semiconductor optical amplifiers (71-7N, 107) each optically coupled to the demultiplexer to amplify a corresponding one of the demultiplexed signals; and a multiplexer (11, 135) made of the semiconductor material and optically coupled to the plurality of semiconductor optical amplifiers to combine the demultiplexed signals amplified by the semiconductor optical amplifiers to produce a multiplexed signal. The demultiplexer, the semiconductor amplifiers and the multiplexer are integrated on a single semiconductor substrate. The demultiplexer and the multiplexer may be implemented by arrayed waveguide diffraction grating structures, and the semiconductor optical amplifiers may be implemented by a semiconductor quantum well structure having well widths ranging from a minimum value to a maximum value. The semiconductor optical amplifiers can provide a gain wavelength bandwidth of 80-800 nm. |
