Abstract
A semiconductor optical amplifier (SOA) receives a multiwavelength input optical signal and amplifies the multiwavelength input optical signal to generate an amplified multiwavelength optical signal. A waveguide is coupled to receive the amplified multiwavelength optical signal. The waveguide includes an enhanced chromatic dispersion segment configured to increase chromatic dispersion experienced by the multiwavelength optical signal as the multiwavelength optical signal propagates through the waveguide and is amplified by the SOA. This increase in chromatic dispersion reduces noise, such as four-wave mixing noise, in the amplified multiwavelength optical signal.
