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 3):
An optical waveguide element comprising:\n an input side; an output side; and an optical waveguide located between the input side and the output side, wherein light applied from the input side propagates through the optical waveguide and emerges at the output side, wherein the optical waveguide includes:\n a slab part in which a maximum thickness of lithium niobate film is a first thickness; and \n a ridge part in which a maximum thickness of lithium niobate film is a second thickness greater than the first thickness, \n wherein the first thickness is 0.05\u00d71.55 \u03bcm or more and less than 0.4\u00d71.55 \u03bcm, wherein a width of the ridge part is 0.1\u00d71.55 \u03bcm or more and less than 1.0\u00d71.55 \u03bcm, and wherein a thickness of the ridge part is 0.5\u00d71.55 \u03bcm or more and less than 2.0\u00d71.55 \u03bcm.
