Optically controlled delay lines by pulse self-trapping in parametric waveguides with distributed feedback

, , and . IEEE J. Quantum Elect. 36 (8): 931--943 (2000)


Quadratically nonlinear waveguides are studied in the presence of a Bragg grating resonant with one of the involved frequencies. In the case of second-harmonic generation and distributed feedback at the fundamental, we investigate the existence and features of two-color gap-solitary waves, focusing on controlling their propagation speed. This leads to the conception of optically controlled delay lines and retiming schemes for pulse streams in communication systems.
