ABSTRACT:
Disclosed is an optical device for the processing of an optical wave by non-linear effects, comprising, on the surface, a guide and doping zones arranged transversally to the direction of the guide. The distribution pitch of these zones is equal to an even multiple of the length of coherence for the interaction envisaged. The length of each zone along the direction of the guide is equal to an odd multiple of the length of coherence.
