  • Patent number: 10627584
    Abstract: A connector that includes an outer housing having an assembly channel with a stopping step on an inner wall of thereof and an optical beam expanding module assembled with the assembly channel of the outer housing. The optical beam expanding module includes a rear seat, formed with a snap ring groove, in which a C-shaped snap ring is fitted. A cable having a strengthening element is fixed on a rear end portion of the rear seat. When the cable of the optical beam expanding module is pulled outwardly, the C-shaped snap ring abuts against the stopping step, so that a pulling force exerted on the cable is transferred to the outer housing through the strengthening element of the cable, instead of being transferred to an optical fiber of the cable, thus preventing the optoelectronic coupling end faces of the connector from being separated.

  • Patent number: 10598875
    Abstract: Disclosed herein are photonic package assemblies, packages, and devices that include photonic dies and optical coupling structures aligned with photonic dies to enable exchange of electromagnetic signals. In one aspect, a photonic package assembly includes a photonic integrated circuit (PIC) die having one or more PICs, and an optical coupling structure (OCS) positioned adjacent to the PIC die such that electromagnetic signals may be exchanged between at least one of the one or more PICs and the OCS. The assembly further includes a structure that forms a bridge, and, thereby, provides mechanical coupling, between the OCS and the PIC die. Providing a bridge structure that directly attaches an OCS to a PIC die may improve achieving and maintaining the desired alignment between the OCS and the PIC die, which may lead to an improved coupling performance over the lifetime of products.
