T. Liang et Rw. Ziolkowski, DISPERSION EFFECTS ON GRATING-ASSISTED OUTPUT COUPLERS UNDER ULTRAFAST PULSE EXCITATIONS, Microwave and optical technology letters, 17(1), 1998, pp. 17-23
The effects of dispersion on the performance of finite-length grating-
assisted output couplers driven by ultrafast pulses are studied. Two d
ifferent FDTD formulations of Lorentz dispersion are treated, and both
dispersive waveguides and grating teeth are considered. The impact of
dispersion on the output beams is quantified. (C) 1998 John Wiley & S
