L. Zhai et al., DIFFRACTION GRATING MODEL FOR TRANSMISSION-LINE LASER MODEL OF ACTIVELY MODE-LOCKED SEMICONDUCTOR-LASERS, IEE proceedings. Optoelectronics, 141(1), 1994, pp. 21-26
A diffraction grating model is developed for use with the transmission
-line laser model to enable accurate simulation of grating-controlled
mode-locked semiconductor lasers. The trade-off between accuracy and c
omputational effort is examined. Asymmetrical detuning characteristics
are investigated using the grating model. The pulsewidth and locking
bandwidth are shown to depend on the bandwidth of the optical system,
which is determined by the grating.
