  • Patent number: 9709760
    Abstract: One example embodiment includes an optical subassembly (OSA). The OSA includes a flex circuit, an optical port, and an active optical component subassembly. The flex circuit is constructed of at least one electrically-conductive layer and at least one electrical insulator layer. The optical port defines a barrel cavity and is mechanically coupled to the flex circuit at a flex connection. The active optical component subassembly is positioned within the barrel cavity and electrically coupled to the flex circuit.

  • Patent number: 8785897
    Abstract: Monolithic opto-isolators and arrays of monolithic opto-isolators are disclosed. The monolithic opto-isolators are manufactured in a single semiconductor wafer where they may be tested at the wafer level before each opto-isolator is singulated from the wafer. The monolithic opto-isolators include a VCSEL monolithically produced adjacent to a photodiode where an axis of optical signal transmission of the VCSEL is substantially parallel to an axis of optical signal reception by the photodiode.

  • Patent number: 7223028
    Abstract: Reducing transmission of electromagnetic waves through a barrel portion of an optical module. A barrel for optically coupling an optical device to an optical fiber within a fiber optic cable can include a plastic portion and a metallic shielding portion for reducing transmission through the barrel. An optical device can be coupled to the plastic portion. The metallic shielding portion can be coupled to the plastic portion and surround at least a portion of the plastic portion. The metallic shielding portion can be shaped and configured so as to reduce transmission of electromagnetic radiation through the barrel.
