Theoretical modeling of tunable three-section slotted Fabry-Perot lasers

We present a time-domain traveling wave dynamic model for simulation of wavelength tunable three-section slotted Fabry-Perot semiconductor lasers. The slot structure is characterized by using the boundary conditions of the optical fields propagating through the slot facets. Static and dynamic wavelength switching characteristics are simulated. Good agreements have been found between the simulation results and the experimental measurements.
