Pulse simulations of a mirrored counterpropagating-QPM device.
A basic mirrored counterpropagating quasi-phase-matched device is studied with a pulsed input fundamental plane wave using the method of lines and the relaxation method. Several examples are given under varying spatial pulse length to device length ratios. An approximate upper bound on the device length is established from this study for practical pulsed applications; the largest usable length is approximately the same as the spatial length of the pulse.
