DISPOSITIF OPTIQUE DE TRAITEMENT D'UNE ONDE OPTIQUE, SON PROCEDE DE REALISATION ET UN DOUBLEUR DE FREQUENCE

Optical device for processing light by non-linear effects, comprising the surface (10), a ferroelectric substrate (1), a guide G1 and zones of doping (ZD1 to ZDn) disposed transversely to the direction of the guide. The pitch for distributing these zones is equal to an even multiple of the coherence...

Beschreibung
Zusammenfassung:	Optical device for processing light by non-linear effects, comprising the surface (10), a ferroelectric substrate (1), a guide G1 and zones of doping (ZD1 to ZDn) disposed transversely to the direction of the guide. The pitch for distributing these zones is equal to an even multiple of the coherence length for the envisaged interaction. The length of each zone, along the direction of the guide, equals an odd multiple of the coherence length. APPLICATIONS: frequency-doubling device, light emission in the blue.
