Abstract: A method and an apparatus for coupling an optical waveguide to a single-mode fiber are disclosed. The apparatus includes a substrate, a first optical waveguide, a single-mode fiber and a second optical waveguide. The first optical waveguide, the single-mode fiber and the second optical waveguide dispose on the substrate. One end of the single-mode fiber has an optical fiber taper structure. One end of the second optical waveguide is optically coupled to the first optical waveguide. Another end of the second optical waveguide is optically coupled to the single-mode fiber using the optical fiber taper structure of the single-mode fiber.

Abstract: This application provides a two-segment DBR laser and a monolithically integrated array light source chip, and relates to the field of optical communications. The two-segment DBR laser includes a grating region, a gain region, and a broadband reflector. The grating region and the broadband reflector are respectively disposed at two ends of the gain region. The grating region includes a first bottom liner, a first support structure, a first ridge waveguide structure, and a first heater. The first ridge waveguide structure is fastened by the first support structure and suspended in midair above the first bottom liner, and the first bottom liner, the first support structure, and the first ridge waveguide structure jointly form a cavity. The first heater is located on a surface that is of the first ridge waveguide structure and that faces away from the cavity.

Abstract: The present invention relates to the field of natural human-computer interaction technologies, and discloses a bioelectricity-based control method and apparatus, and a bioelectricity-based controller, so as to improve naturalness of human-computer interaction. The method is as follows: performing characteristic extraction on a collected surface electromyography signal generated when a user performs a finger press operation, so as to obtain characteristic information; determining, according to a pre-created finger type recognition template, a finger type that is used to perform the finger press operation and that is corresponding to the obtained characteristic information; and mapping the determined finger type used to perform the finger press operation to a corresponding first instruction, and controlling a controlled device according to the first instruction. In this way, the controlled device may be controlled in a more harmonious and natural human-computer interaction manner.
