    摘要: A waveguide includes multiple segments having different bend radii with substantially consistent cure profiles and related methods and systems for making and using the same. The waveguide is formed by modifying a laser beam used to write the waveguide to provide the consistent cure profile in the multiple segments. A marker characteristic of laser writing may be present in the waveguide. A method or system modifies an intensity profile or a shape profile of a laser beam to proactively compensate for exposure convolution based on the geometry of each waveguide segment. A convolution compensator is positioned in the path of the laser beam to modify the beam spot profile during writing to form the multiple segments of the waveguide in a photo-curable layer.

    摘要: An apparatus and system that includes a plurality of data devices, a network module, and a chassis. The network module may include an interface defining couplings and channels extending between the couplings defining a network topology for interconnecting data devices. The chassis may be configured to receive data devices and the network module to operably couple the received data devices via the interconnect topology defined by the network module.

    摘要: Optical connectors may include various portions, or structures, to provide a plurality of degrees of movement to optical ferrules. The optical ferrules may be linearly movable along one or more axes and rotationally moveable about one or more axes for alignment and coupling to corresponding optical ferrules. The optical connectors may be integrated with, or in conjunction with, other non-optical connectors such as electrical connectors, e.g., located on a drive carrier.

    摘要: A system includes a first optical communication interface and a second optical communication interface optically coupled via a free-space communication channel. The interfaces are spaced at variable distances. Each interface includes an optical source to provide a beam of electromagnetic energy and an optical receiver to receive the beam to bi-directionally communicate with the other interface via the channel. The first optical communication interface may be coupled to a sub-chassis. The second optical communication interface may be coupled to a device frame. The device frame may be movably coupled to the chassis. Communication may utilize multi-input, multi-output processing configured by a calibration matrix. A shutter may be positioned to receive the beam or be positioned clear of the beam depending on the distance between the interfaces.

    摘要: A waveguide includes a segment with a substantially uniform cure profile and related methods and systems for making and using the same. The waveguide is formed by modifying a laser beam used to write the waveguide to provide a substantially uniform cure profile in the waveguide. A marker characteristic of laser writing may be present in the waveguide. A method or system modifies an intensity profile or a shape profile of a laser beam to proactively compensate for exposure convolution based on the characteristics of the laser beam spot profile. A convolution compensator is positioned in the path of the laser beam to modify the beam spot profile during writing to form the one or more segments of the waveguide in a photo-curable layer.

    摘要: The exemplary systems, apparatus, structures, and methods may include an assembly including substrate, an optical waveguide, and an optical access associated with the optical waveguide. Light from the optical access may be measured along the optical waveguide. The coupling loss of the optical waveguide may be determined based on at least the light measurements from the optical access.
