Abstract: An optical interconnect arrangement for use in transmitting light between a photonic integrated circuit and a plurality of optical fibres, comprises a plurality of primary optical beam management elements, a plurality of secondary optical beam management elements, and a plurality of optical fibre alignment structures. Each optical fibre alignment structure is configured to receive a corresponding optical fibre so that the end of the corresponding optical fibre is aligned with, but separated from, a corresponding one of the secondary optical beam management elements, and the optical interconnect arrangement defines a plurality of optical paths, each optical path extending from a surface of the optical interconnect arrangement to the end of a corresponding one of the optical fibre alignment structures via a corresponding one of the primary optical beam management elements and a corresponding one of the secondary optical beam management elements. An optical system is also disclosed which comprises the optical interconnect arrangement, a photonic integrated circuit, and a plurality of optical fibres.

Abstract: An optical apparatus (10) for routing an optical signal (12) comprises a body (14) comprising a material. A waveguide (16) is formed in the body (14) by laser modification of the material. The optical apparatus (10) further comprises a region (18) comprising a lower refractive index than the material of the body (14) and defines an interface (24) between the region (18) and the waveguide (16). The waveguide (16) and the interface (24) are aligned relative to each other for routing the optical signal (12) therebetween and reflecting the optical signal (12) at the interface (24).

Abstract: The present application relates to a method for modifying a substrate, which comprises generating a pulsed laser beam comprising a train of laser pulses, the train of laser pulses including at least three consecutive laser pulses, and controlling a direction of the pulsed laser beam and/or a position of the substrate from laser pulse to laser pulse so that the at least three consecutive laser pulses sequentially irradiate at least three regions of the substrate according to a predetermined spatial sequence which defines the relative spatial positions of the at least three regions of the substrate and the order of irradiation of the at least three regions of the substrate. The present application relates also to an apparatus (100) for modifying a substrate (108). The method and apparatus (100) may be used, in particular though not exclusively, for forming an optical device.

Abstract: An optical interconnect component for use in transmitting light between a photonic integrated circuit and one or more optical fibres attached to an optical fibre connector ferrule is disclosed. The optical interconnect component comprises a step formed at an edge of the optical interconnect component, the step including a ledge and a facet, one or more optical beam management elements formed in a surface of the optical interconnect component, and a plurality of integrated optical waveguides. Each of two or more of the integrated optical waveguides extends from the facet so as to define a plurality of optical ports at the facet, and each of the one or more optical beam management elements is aligned with, but separated from, an end of a corresponding one of the plurality of integrated optical waveguides. Also disclosed are an optical fibre connector ferrule, an optical interconnect assembly comprising the optical interconnect component and the optical fibre connector ferrule, and an optical system comprising the optical interconnect assembly, a photonic integrated circuit, and one or more optical fibres.

Abstract: An apparatus for positioning one or more optical fibers relative to the apparatus, comprises a body comprising a monolithic block of material, one or more fiber alignment structures formed in the material of the monolithic block, each fiber alignment structure comprising a groove configured to accommodate a corresponding optical fiber, and one or more apparatus alignment features formed in the material of the monolithic block, wherein the one or more apparatus alignment features are additional to the one or more fiber alignment structures and wherein the one or more apparatus alignment features have a known spatial relationship relative to the one or more fiber alignment structures. The one or more apparatus alignment features may enable passive alignment of the apparatus relative to a member which is separate from the apparatus such as an optical component and/or a photonic chip. When one or more optical fibers are located and/or secured in one or more corresponding fiber alignment structures of the apparatus, the one or more apparatus alignment features may also enable passive alignment of the one or more optical fibers relative to the member.

Abstract: An apparatus for positioning one or more optical fibers relative to the apparatus, comprises a body comprising material, and one or more fiber alignment structures defined in the material of the body, wherein each fiber alignment structure is configured to accommodate a corresponding optical fiber, and wherein each fiber alignment structure is configured to induce one or more bends along the corresponding optical fiber. When an optical fiber is located in such a fiber alignment structure, the optical fiber may be forced into contact with the fiber alignment structure in one or more known regions so that the corresponding optical fiber is located at a more predictable position relative to the corresponding fiber alignment structure in the one or more known regions than is the case for known fiber alignment structures. The location of the corresponding optical fiber at a more predictable position may improve the optical coupling efficiency achievable between the optical fiber and an optical component and/or a photonic chip.
