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

1-81. (canceled)
A fiber optic communication system, comprising:
- an optical signal source for producing an optical signal;
- a transmission medium having an associated dispersion Df;
- a frequency modulator between the optical signal source and the transmission medium adapted to at least partially frequency modulated the optical signal;
- and
- an optical discriminator having an associated dispersion Dd adapted to convert the partially frequency modulated signal into a substantially amplitude modulated signal, where the associated dispersion Dd has either a positive or negative sign, where the sign Dd is an opposite sign of Df.

A fiber optic communication system, comprising:
- an optical signal source adapted to produce a partially frequency modulated signal;
- a first optical discriminator adapted to convert the partially frequency modulated signal into a substantially amplitude modulated signal;
- and
- a second optical discriminator having an associated dispersion Dd adapted to receive the substantially amplitude modulated signal and compensate for at least a portion of a dispersion Df in a transmission medium, where Dd is the opposite sign of Df.
