Abstract

DFB laser intermodulation distortion were theoretically analyzed, taking longitudinal electrical field distribution in the laser cavity into account. The modulation distortion mechanism caused by longitudinal electrical field nonuniformity along the laser cavity was theoretically clarified. Furthermore, theoretical law distortion yields, which are decided by the uncontrollable grating phases at cleaved facets, were calculated for devices with various kL values and facet reflectivities, in order to obtain desirable design for the lasers used for subcarrier multiplexing.
