| 英文摘要 | An improved multi-channel optical equalizer method and apparatus for intersymbol interference mitigation compensates many wavelength channels simultaneously and requires few adjustable parameters. The equalizer unit has only two control signals, one to control signal magnitude and one to control signal phase, yet it can still compensate many wavelength channels simultaneously. The equalizer includes a coupler with a controllable coupling ratio for splitting the light into two portions and a controllable interferometer means having two arms, one arm having an additional delay which is equal to an integer multiple of 1/Deltaf, where Deltaf is the channel spacing of the multiwavelength system. The controllable interferometer unit also has a controllable delay in a first or second arm for adjusting the relative phase of the light passing therethrough. A coupler combines the two signal portions from the first and second arms to form the equalized output signal. |
