ABSTRACT:
Non-linear optical devices incorporating an integrated waveguide on a substrate, also relating to a non-linear optical device utilizing a passive layer covering the integrated waveguide making it possible by increasing the effective index ranges of the fundamental and harmonic radiations to obtain a phase matching for two propagated modes having an increased overlap integral value. The invention is more particularly applicable to frequency doubling making it possible to obtain a visible radiation source from a primary source functioning in the very-near infrared region.
