Abstract: An LBM package and method for packaging an LBM using a stamped metallic mirror array that folds light beams, correct beam shapes, fold and/or redirect beam propagations. The mirror array can be integrated or assembled inside an LBM to provide beam shaping and redirection of the high-power beams near the laser diode. The LBM incorporates a stamped metallic freeform mirror or reflector with an off-axis parabolic shape is configured to fold and collimate laser beam. A precision stamping process is deployed to produce an array of miniature, freeform mirrors in high volume applications. The mirror array simplifies the optical path and eliminates passive components such as refractive lenses and dichroic filters that combine RGB beams. Stamped metallic optical components with micro-scale freeform mirrors in the LBM are tolerant of high temperatures and can thermally diffuse heat away from the reflective surface for high power applications.

Abstract: A passive optical alignment coupling between an optical connector having a first two-dimensional planar array of alignment features and a foundation having a second two-dimensional planar array of alignment features. One of the arrays is a network of orthogonally intersecting longitudinal grooves defining an array of discrete protrusions that are each in a generally pyramidal shape with a truncated top separated from one another by the orthogonally intersecting longitudinal grooves, and the other array is a network of longitudinal cylindrical protrusions. The cylindrical protrusions are received in the grooves, with protrusion surfaces of the cylindrical protrusions in contact with groove surfaces and the top of the discrete protrusions contacting the surface bound by the cylindrical protrusions. The optical connector is removably attachable to the foundation to define a demountable coupling, with the first array of alignment features against the second array of alignment features to define an elastic averaging coupling.

Abstract: An optical bench subassembly including an integrated photonic device. Optical alignment of the photonic device with the optical bench can be performed outside of an optoelectronic package assembly before attaching thereto. The photonic device is attached to a base of the optical bench, with its optical input/output in optical alignment with the optical output/input of the optical bench. The optical bench supports an array of optical fibers in precise relationship to a structured reflective surface. The photonic device is mounted on a submount to be attached to the optical bench. The photonic device may be actively or passively aligned with the optical bench. After achieving optical alignment, the submount of the photonic device is fixedly attached to the base of the optical bench. The optical bench subassembly may be structured to be hermetically sealed as a hermetic feedthrough, to be hermetically attached to a hermetic optoelectronic package.

Abstract: Lockable connector and adapter assembly with a rear body having a shield to prevent unlocking of the connector from the adapter port unless the connector is unlocked with a key configured for the connector. The lockable connector is a MPO connector with a slidable outer housing configured to receive a key latch arm of specific configuration to unlock the MO connector from the adapter port. The key latch arms or separate keys form the combination unlocking the MPO connector from the adapter port.

Abstract: An optical connector holding two or more LC-type optical ferrules is provided. The optical connector includes an outer body, an inner front body accommodating the two or more LC-type optical ferrules, ferrule springs for urging the optical ferrules towards a mating connection, and a back body for supporting the ferrule springs. A removable inner front body for polarity change is disclosed. A multi-purpose rotatable boot assembly for polarity change is disclosed. The multi-purpose boot assembly can be pushed and pulled to insert and remove the micro connector from an adapter receptacle.
