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 2):
An optical modulator comprising:\n an optical waveguide element; and a multimode interference branching waveguide in which a propagation loss is larger in a m=1 mode than in a m=0 mode, the multimode interference branching waveguide being connected to the optical waveguide element, wherein the optical waveguide element comprising:\n an input side; \n an output side; and \n 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, \n 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 times or more and less than 0.4 times a wavelength of the light, wherein a width of the ridge part is 0.1 times or more and less than 1.0 time the wavelength of the light, and wherein a thickness of the ridge part is 0.5 times or more and less than 2.0 times the wavelength of the light.
