Publication number: 20080193073Abstract: Amorphous and crystalline potassium lithium tantalate niobate (KLTN) structures for electro-optic devices. Amorphous regions are formed in KLTN crystal by ion bombardment using light ions (protons, helium etc.) >1 MeV. Amorphous regions (cladding) have a lower refractive index (n) than the crystalline material to define waveguide regions in crystals. Selective bombardment via a metal shadow mask produces produce three dimensional structures for: ring resonators, tunable electro-optic resonators, electroholographic alpha gratings, photonic crystals and modulators. Vertical layers of amorphous/crystalline material form a Bragg grating (Raman-Nath diffraction). KLTN (ferroelectric with oxygen perovskite structure) has a large quadratic electro-optic effect in paraelectric phase above the composition dependent Curie (transition) temperature TC.Type: ApplicationFiled: April 9, 2006Publication date: August 14, 2008Applicant: Yissum Research Development CompanyInventor: Aharon Agranat
