Patent number: 11662508Abstract: In some implementations, an optical assembly comprises an optical cavity; one or more detectors; and an optical component having an input face and an output face configured to receive an input beam to the input face and to produce one or more primary output beams, and a plurality of secondary output beams from the output face, the secondary output beams resulting from multiple internal reflections within the optical component. At least one of the input face is not perpendicular to the input beam or the output face is not perpendicular to the one or more primary output beams. Each primary output beam is transmitted through the optical cavity perpendicular to at least one surface of the optical cavity, and directed to a respective one of the one or more detectors. Each detector is arranged to exclude at least a portion of each secondary output beam.Type: GrantFiled: November 15, 2021Date of Patent: May 30, 2023Assignee: Lumentum Operations LLCInventors: Adrian Perrin Janssen, Robert Simpson, Paul Firth

Patent number: 9509118Abstract: The invention relates to an optoelectronic assembly. The optoelectronic assembly comprises one or more optoelectronic components and a housing. The housing comprises an outer wall electrically connected to the one or more optoelectronic elements. The housing is configured to provide an electrical interface between the one or more optoelectronic components and an external electronic device. The electrical connection between the outer wall and the one or more optoelectronic components comprises an electrically conductive element. The electrically conductive element is supported on a dielectric material, such that the dielectric material provides structural support to the electrically conductive element between the one or more optoelectronic components and the outer wall.Type: GrantFiled: September 27, 2013Date of Patent: November 29, 2016Assignee: Oclaro Technology LimitedInventor: Paul Firth

Patent number: 8687279Abstract: The invention relates to a lens comprising two or more seating surfaces and an optical axis offset from the center of the lens such that the optical axis is spaced by a first distance from a first seating surface and by a second distance from a second seating surface. The first and second distances are different so that the lens can be orientated to provide at least two different optical axis heights depending upon which seating surface is chosen to seat the lens.Type: GrantFiled: July 11, 2012Date of Patent: April 1, 2014Assignee: Oclaro Technology LimitedInventor: Paul Firth
