Abstract

This invention generally relates to an optical filter (304-306) for a fiber optic communication system (100). An optical filter (304-306) may be used, following a directly modulated laser source (102), and converts a partially frequency modulated signal into a substantially amplitude modulated signal. The optical filter (304-306) may compensate for the dispersion in the fiber optic transmission medium (108) and may also lock the wavelength of the laser source (102).
