Abstract:
An apparatus for transmitting a light signal, comprising:a first fiber for transmitting the light signal therethrough;a phase conjugator which receives the light signal from the first fiber and produces a corresponding phase conjugate light signal; anda second fiber which receives the phase conjugate light signal from the phase conjugator and transmits the phase conjugate light signal therethrough, whereinthe first and second fibers each have an associated dispersion, length, light intensity, and nonlinear refractive index,the ratio of the dispersion of the first fiber to the dispersion of the second fiber is substantially equal to the ratio of the length of the second fiber to the length of the first fiber, andthe ratio of the product of the optical frequency, the light intensity and the nonlinear refractive index of the first fiber to the product of the optical frequency, the light intensity and the nonlinear refractive index of the second fiber is substantially equal to the ratio of the length of the second fiber to the length of the first fiber.
