The optical pulse string conversion device, according to the optical pulse string generator and the optical pulse string

摘要

PROBLEM TO BE SOLVED: To output an optical pulse train of which the repetition frequency has been converted to a lower value substantially without loss.;SOLUTION: An optical pulse train conversion apparatus includes: a phase modulation par 21 which subjects an input optical pulse train to phase modulation in accordance with a phase modulation signal; and a group velocity dispersion part 22 which gives group velocity dispersion necessary for a partial temporal Talbot effect to the optical pulse train subjected to the phase modulation to output an optical pulse train of which the repetition frequency has been reduced.;COPYRIGHT: (C)2010,JPO&INPIT
