    摘要： An optical module according to the present invention includes: an optical device including an optical waveguide chip; an optical fiber block bonded to and arranged on an end face of the optical waveguide chip; an optical fiber that has one end optically connected to the optical waveguide chip via the optical fiber block; an optical fiber holding mechanism for holding the other end of the optical fiber; and an optical fiber carrier. The optical fiber is arranged while being curved from the optical fiber carrier toward the optical fiber block in a U-shape, and a wall structure is formed on the surface of the carrier while being adjacent to the optical fiber at, for example, a position on the outer side of the U-shaped curve of the optical fiber position at which the wall structure reduces a normal force of the optical fiber.

    摘要： A system for laser welding a fiber to a substrate is provided. The system comprises a fiber having a first end, a substrate defining a surface, a coating, a laser configured to emit photonic energy, one or more processors, and memory. The memory includes computer readable code configured to, when executed, cause the processor(s) to perform various tasks. The tasks include positioning the fiber relative to the substrate so that the first end of the fiber is positioned proximate to the surface of the substrate with the coating positioned between the fiber and the substrate. The tasks also include positioning the laser relative to the fiber or the substrate. The tasks also include causing the laser to emit photonic energy through the fiber or through the substrate. Emission of the photonic energy through the fiber or through the substrate causes the fiber to be laser welded to the substrate.

    摘要： A hybrid rotary joint provides both optical and fluid channels for applications such as optogenetic research. The rotary joint has a stationary component and a rotating component. The optical channel and fluid channel permit simultaneous and rotation-insensitive passage of light and fluid from the stationary to the rotating side of the hybrid rotary joint. The input to the optical channel is provided via an input optical fiber and the input to the fluid channel is fluid from a fluid source. The outputs are an optical fiber output and a fluid channel output. As light passes from the stationary side to the rotating side of the hybrid rotary joint, it is deflected off a beam deflector having an angular orientation that is passively aligned and made independent of the angular orientation of the rotating component via the interaction between magnets attached to each of the beam deflector and the stationary component.
