SINGLE SIDE BAND OPTICAL FREQUENCY COMB GENERATION METHOD AND APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a single side band optical frequency comb generator of a novel system using a light signal circulation loop including an optical modulator of a two-electrode structure and an optical fiber amplifier. SOLUTION: The optical modulator and the optical amplifier are arranged in an optical fiber loop. Only the one side band signal of a reference signal is formed by this optical modulator and is circulated in the loop described above while the loss thereof is compensated by the optical amplifier, by which only the grid component of the frequency axis is formed to a wide band in the output.
