Conversion of a wideband frequency-modulated signal to amplitude modulation through dispersion in an optical fiber.
Our calculation shows that, by means of group-velocity dispersion of an optical fiber, a cw frequency-modulated signal evolves into an intense and sharp pulse. The results compare favorably with an earlier analysis of a narrowband FM system. In particular, the minimum fiber length needed for maximum FM-AM conversion may be considerably reduced.
