Abstract:
An apparatus, comprising:a chromatic dispersion compensation module that includes an input fiber having a first core with a center; an output fiber having a second core with a center, the input fiber is adjacent to the output fiber, spacing between the center of the first core and the center of the second core is affixed to less than one hundred and twenty microns; a lens, the input fiber to route an optical signal to the lens; an etalon resonator having reflectors with fixed reflectivity and a variable optical length to induce a wavelength-dependent delay into the optical signal, the lens to route the optical signal to the etalon resonator; the etalon resonator to route the optical signal to the output fiber through the lens; and two or more chromatic dispersion compensation modules cascadedly connected together.
