Abstract:
Disclosed herein is an optical waveguide element that includes a substrate and a waveguide layer formed on the substrate and comprising lithium niobate. The waveguide layer has a slab part having a predetermined thickness and a ridge part protruding from the slab part. The maximum thickness of the slab part is 0.05 times or more and less than 0.4 times a wavelength of a light propagating in the ridge part.

Claim (Index 4):
An optical waveguide element comprising:\n a substrate; and a waveguide layer formed on the substrate and comprising lithium niobate, wherein the waveguide layer has a slab part having a predetermined thickness and a ridge part protruding from the slab part, the slab part having inclining parts located at both sides of the ridge part, the inclining parts being gradually thinned away from the ridge part, and wherein a maximum thickness of the slab part is 0.05\u00d71.55 \u03bcm or more and less than 0.4\u00d71.55 \u03bcm.
