An optical control device having a substrate 1 formed with an optical waveguide, in which the substrate is a thin plate with a thickness of 10 μm or less, at least a portion of the optical waveguide is configured as a ridge waveguide 21, a trench 20 having a width of 10 μm or less is formed on both sides of at least portions of the ridge waveguide, and a taper waveguide section (area B) continuously changes a light propagation mode of the waveguide between a single-mode and a multi-mode by continuously changing the width or depth of the trench. Additionally, it is desirable that the taper waveguide section is disposed at least in one of a light input section and a light output section, and light propagating through the waveguide is in the single-mode in a section in which the taper waveguide section is disposed.

摘要： An example method of forming a deterministic thin film from a crystal substrate is described herein. The method can include implanting ions into a surface of the crystal substrate to form a thin film crystal layer, and bonding the crystal substrate and a handle substrate to form a bilayer bonding interface between the crystal substrate and the handle substrate. The method can also include exfoliating the thin film crystal layer from the crystal substrate, patterning the thin film crystal layer to define a deterministic thin film, etching one or more trenches in the thin film crystal layer, etching the bilayer bonding interface via the one or more trenches, and releasing the deterministic thin film from the handle substrate.

摘要： According to the invention, a film of optoelectric single crystal may be formed on a substrate made of optoelectric single crystal by a liquid phase epitaxial process. The process comprises the steps of producing a melt of a solute and a melting medium, a solid phase and a liquid phase coexisting in the melt; then cooling the liquid phase for producing super cooling state in the liquid phase; and contacting the substrate to the liquid phase to form the film on the substrate by an epitaxial growing process. The film may be produced on the substrate, the film having a half value width of an X-ray rocking curve not more than that of the substrate.
