PULSE DELAY QUANTITY CORRECTOR AND POLARIZATION MODE DISPERSION COMPENSATOR USING THE CORRECTOR

摘要

PROBLEM TO BE SOLVED: To provide a pulse delay amount corrector which can be manufactured at a low cost and miniaturized and a polarization mode dispersion compensator using the corrector.;SOLUTION: A polarization controller 12 and the pulse delay amount corrector 13 are formed on the same ferroelectric substrate 14 to obtain the polarization mode dispersion compensator 11. The corrector 13 is constituted by arraying TE-TM mode conversion parts 20 to 23 for converting a TE mode to a TM mode or vice versa along an optical waveguide 15 in series so as to convert the delayed TE mode into the TM mode and convert the advanced TM mode into the TE mode by using any one of the mode conversion parts 20 to 23.;COPYRIGHT: (C)2003,JPO
