    Abstract: A diffractive optical element and a terminal device are disclosed. The diffractive optical element includes grating components periodically distributed in a first dimension. The grating component includes N optical waveguides. The N optical waveguides include M optical waveguides that periodically change in a second dimension. At least two of the M optical waveguides that periodically change in the second dimension have different structures. An included angle between the second dimension and the first dimension is greater than 0 degrees and less than 180 degrees. N is an integer greater than 1. M is an integer greater than 1 and not greater than N.

    Abstract: An optical display element includes a plurality of stripes. The plurality of stripes are arc-shaped and have a same bending direction, and the plurality of stripes are configured to reflect operating light of the optical display element, so that the operating light is imaged. Each stripe of the plurality of stripes includes a plurality of resonance elements, and the operating light generates a resonance effect in one or more of the resonance elements.

    Abstract: An optical waveguide component, a preparation method therefor, and an electro-optic modulator are disclosed. The optical waveguide component includes an insulating substrate, a waveguide core, at least two electrodes, and a cladding layer. The at least two electrodes and the waveguide core are all disposed on the insulating substrate, the at least two electrodes are distributed on two sides of the waveguide core, and the cladding layer covers at least a part of an outer wall of the waveguide core. The waveguide core includes an electro-optic material having an electro-optic effect. A refractive index of the insulating substrate is less than a refractive index of the waveguide core. A refractive index of the cladding layer is greater than the refractive index of the waveguide core.
