... used to realize new geometries which can take the performance to unprecedented levels. In particular we will review recent results on the use of domain inversion on a micron scale to improve the electro-optic response of LiNbO3 waveguide modulators in terms of bandwidth and driving voltage. These ap ...

Gap solitons result from the balance of nonlinearity and the effective linear dispersion of a coupled system, e.g., counterpropagating waves in a grating structure, and appear in the gaps associated with avoided crossings. Gap solitons have previous ...
