Abstract
AbstractA split‐step time‐domain modeling is applied to investigate the characteristics of dual‐mode distributed feedback (DFB) laser diode (LD) for terahertz (THz) wave generation. The THz wave generation from 163 to 1,378 GHz by proper thermo‐optic tuning and initial detuning combination is effectively simulated, which is qualitatively analogous to the experimental results. It is shown that the residual facet reflectivity should be below 0.003 to suppress the facet‐to‐facet cavity modes and provide good spectral quality. The time‐domain simulation tool could be incorporated into future THz fiber‐optic communication systems.
