    Abstract: Disclosed are optical connectors and methods for making the same. In one embodiment, the optical connector comprises an optical body, one or more first magnetic materials attached to the optical body, a housing, and one or more second magnetic materials attached to the housing. The first magnetic material(s) provide alignment with an optical element of a complimentary receptacle and the optical body may include one or more openings for receiving the first magnetic materials. The second magnetic material(s) attached to the housing provide retention of the optical connector with the complimentary receptacle when mated together. Consequently, the optical connector allows for quick and easy assembly along with a robust structure for a large number of mating/unmating cycles. In other embodiments, the optical devices disclosed may further include one or more electrical contacts for making a hybrid connection or have a TIR surface integrated into a portion of a housing.

  • Patent number: 9473239
    Abstract: Systems and methods of aligning an optical interface assembly with an integrated circuit (IC) are disclosed. The method includes emitting light from an optical transmitter, passing the emitted light through the optical interface assembly in a first direction, and reflecting the emitted light from a reflective surface disposed immediately adjacent a front end of the optical interface assembly to define reflected light that travels back through the optical interface assembly in a second direction that is substantially opposite the first direction. The reflected light is received by an optical receiver that generates in response a receiver signal. The relative position of the optical interface assembly and the IC is adjusted to achieve an aligned position based on the receiver signal. The disclosure is also directed to a test plug for aligning an optical interface assembly to the IC.

  • Patent number: 9423577
    Abstract: Optical receptacles having compliance for facilitating alignment with fiber optic connectors during insertion, and related components, systems and methods are disclosed. In one example, an optical receptacle disposed in a receptacle optical assembly optically connects to a fiber optic component, for example, a ferrule, for facilitating transmission of an optical signal from the optical receptacle to the exemplary ferrule. A support interface between the optical receptacle and receptacle housing contains a compliance feature that permits the optical receptacle to move with respect to the receptacle housing during insertion of the fiber optic connector. An insertion force of the fiber optic connector causes the optical receptacle to be able to move into optical alignment with the connector during insertion of the fiber optic connector, thereby moving ferrule(s) of the fiber optic connector into optical alignment with the ferrule(s) of the optical receptacle.

  • Patent number: 9389371
    Abstract: A fiber optic connection system is disclosed for optically connecting a fiber optic connector to an internal optical interface of a device through a display surface of the device. Connecting the connector to the device causes a display alignment feature of the connector to be retained against the display surface of the device. This causes a connector optical interface in the connector to optically connect to a device optical interface through the display surface of the device when the connector is connected with the device. One benefit of this arrangement is that a device, such as a smartphone or other small form-factor device for example, may include optical communication hardware that leverages the excellent clarity and flatness of the display surface, such as a display glass for example, to form and maintain a strong fiber optic connection between the connector and the device.

  • Publication number: 20150268431
    Abstract: Embodiments include a fiber organizer comprising an optical interface having a plurality of optical interface-side fiber positions arranged in a linear array, and a cable-side interface having at least two pluralities of cable-side fiber positions each arranged in a linear array. The at least two pluralities of cable-side fiber positions are not collinear with each other, and in some embodiments define a two-dimensional array. A plurality of optical fiber paths extend between the optical interface-side and the cable-side of the fiber organizer such that each optical fiber extends between one of the optical interface-side fiber positions and one of the cable-side fiber positions. Because the transition from a compact bundle of fibers to a linear array occurs within the fiber organizer residing within the plug connector rather than the boot assembly, the boot assembly can be made more compact and ergonomic.
