Abstract: Based on coupling-wave equation,two-segment DFB lasers have been analyzed,and implicit expression of their carrier density and emission wavelength has been obtained.As a special case,the oscillation behaviors of the absorptive device with two equal-length segments:threshold conditions,carrier density and wavelength tuning range have been analyzed.
