Patent number: 11931977Abstract: A method of fabricating a multi-core polymer optical fibre comprises arranging optical fibre preforms in a stack, the optical fibre preforms each comprising a polymer core and polymer cladding surrounding the polymer core; and drawing and bonding the stack to form the multi-core polymer optical fibre. Any contaminants or impurities which collect on outer surfaces of the preforms may be confined to boundaries between the preforms, which may avoid attenuation of signals passed through the cores while at the same time reducing crosstalk between cores of the final manufactured fibre. Also provided is a multi-core polymer optical fibre obtainable by the method.Type: GrantFiled: March 31, 2022Date of Patent: March 19, 2024Assignee: Microsoft Technology Licensing, LLCInventors: Paolo Costa, Gilberto Brambilla, Kai Shi, Hitesh Ballani, Richard James Baca

Patent number: 11855690Abstract: A system for using free-space optics to interconnect a plurality of computing nodes can include a plurality of optical transceivers that facilitate free-space optical communications among the plurality of computing nodes. The system may ensure a line of sight between the plurality of computing nodes and the optical transceivers to facilitate the free-space optical communications. The line of sight may be preserved by the position or placement of the computing nodes in the system. The position or placement of the computing nodes may be achieved by using different shaped enclosures for holding the computing nodes.Type: GrantFiled: November 29, 2021Date of Patent: December 26, 2023Inventors: Winston Allen Saunders, Christian L.

Publication number: 20230314695Abstract: A multi-core optical fibre comprises a plurality of cores embedded in cladding. The cladding comprises a polymer. The cladding has an outer cross-sectional shape with an order of rotational symmetry of less than or equal to 4. By limiting the rotational symmetry of the multi-core optical fibre, rotational alignment of the cores with light sources/light detectors may be made easier. Also provided are optical cables and kits including the multi-core optical fibre, and a method of fabricating a multi-core polymer optical fibre.Type: ApplicationFiled: March 31, 2022Publication date: October 5, 2023Inventors: Paolo COSTA, Gilberto BRAMBILLA, Kai SHI, Hitesh BALLANI, Richard James BACA

Publication number: 20230314696Abstract: A method of fabricating a graded-index polymer optical fibre comprises preparing a cladding composition, the cladding composition comprising either a mixture of a cladding polymer and a dopant or a mixture of a cladding polymer precursor and a dopant; forming cladding from the cladding composition around a core, the core comprising a core polymer; and causing diffusion of the dopant into the core such that the dopant has a continuous concentration gradient, according to which concentration gradient the concentration of the dopant increases with radial distance from a centre of the core. The dopant is a compound having a refractive index which is lower than a refractive index of the core polymer. By distributing the dopant such that the dopant concentration is lowest at the centre of the core, the optical attenuation of the graded-index polymer optical fibre may be reduced. Also provided is a graded-index polymer optical fibre obtainable by the method.Type: ApplicationFiled: March 31, 2022Publication date: October 5, 2023Inventors: Paolo COSTA, Gilberto BRAMBILLA, Kai SHI, Hitesh BALLANI, Richard James BACA
