Embodiment Construction

[0072] Embodiments described herein relate to optical assemblies, lens-based connectors, and methods of manufacturing optical assemblies and lens-based connectors. Embodiments of the present disclosure position a precisely matched lens array in front of the fiber endface and enable connector-to-connector mating in the axially and laterally permitted expanded beam space. More specifically, embodiments provide High Fiber Count Extended Beam Connectors (HFC / EB) that have precisely formed matching arrays of holes and lenses, precisely and permanently connecting these two elements with their mating optical fibers Such subassemblies are mounted together and contained in a connector body that controls all necessary degrees of freedom for successful optical coupling. Embodiments ensure accurate positioning of the lens array and fiber array within the body of a lens-based optical connector such as an HFC / EB connector.

[0073] The embodiments described herein effectively establish a s...

Abstract

Lens-based optical connector assemblies and methods of fabricating the same are disclosed. In one embodiment, a lens-based connector assembly includes a glass-based optical substrate including at least one optical element within the optical substrate, and at least one alignment component positioned at an edge of the glass-based optical substrate, wherein the at least one alignment component is located within 0.4 [mu]m of a predetermined position with respect to the at least one optical element along an x-direction and a y-direction. The lens-based connector assembly further includes a connector element including a recess having an interior surface. The interior surface has at least one connector alignment component. The glass-based optical substrate is disposed within the recess such that the at least one alignment component of the glass-based optical substrate engages the at least one connector alignment component.

Description

[0001] related application [0002] This application claims the benefit of priority to US Application No. 16 / 778,000, filed January 31, 2020, the contents of which are relied upon and incorporated herein by reference in their entirety. technical field [0003] The present disclosure relates generally to optical connections, and more particularly to lens-based connector assemblies having alignment features fabricated by a laser process. Background technique [0004] Advantages of optical communication include extremely wide bandwidth and low noise operation. Because of these advantages, optical fibers are increasingly being used for a variety of applications including, but not limited to, broadband voice, video, and data transmission. Connectors are commonly used in data centers and telecommunications systems to provide service connections to rack-mounted equipment and to provide inter-rack connections. [0005] Optical interconnects in data centers use cables containing hu...
