Mode stability of a two-wavelength Fabry-Perot/distributed-feedback laser

A theory based on a Fokker-Planck equation has been developed to analyze the two-mode operation of a Fabry-Perot/distributed-feedback (FP/DFB) laser. Simultaneous oscillation of the DFB mode and the FP mode near the gain peak with negligible mode power fluctuation can be achieved if the DFB mode is detuned sufficiently from the gain peak. Calculated results for the design of stable two-wavelength lasers are presented.<
