| Outline of Final Research Achievements |
Experimental work was performed on the titled subject. Techniques were established for formation of LiNbO3 channel waveguides by surface-activated direct bonding, slicing with He ion implantation and proton-exchange-accelerated chemical etching. Channel waveguides of 0.7×1.0 squared micron cross section and a nonlinear-optic coupling coefficient one order of magnitude larger than that of conventional waveguides were obtained. Formation of quasi-phase matching (QPM) structures was accomplished by domain inversion with charge-controlled pulse voltage application to implement nano-waveguide QPM nonlinear optic wavelength conversion devices. The results include formation of waveguides and QPM structures in new crystals MgO:c-LiTaO3 with high optical damage resistance and LaBGeO5 with wide ultraviolet transparency range.
