Abstract

The effects of dispersion on the performance of finite-length grating-assisted output couplers driven by ultrafast pulses are studied. Two different 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.
