Hermetic optical fiber alignment assembly having integrated optical element

a technology of optical fiber and alignment assembly, which is applied in the field of optical fiber ferrule structures, can solve the problems of not being suitable for use in smaller electronic devices, not supporting the optical fiber with any positional alignment with respect to the sleeve, and being comparatively large in size for a given port count, so as to improve the efficiency of optical alignment, reduce costs, and facilitate use.

Problems solved by technology

Given the large clearance between the sleeve and the optical fiber and the use of epoxy to seal such clearance (i.e., a layer of epoxy between the external fiber wall and the inside wall of the sleeve), the sleeve does not support the optical fiber with any positional alignment with respect to the sleeve.
The transmitters and receivers and associated optical elements and connection structures are therefore generally bulky, which take up significant space, thereby making them not suitable for use in smaller elect

Abstract

A hermetic optical fiber alignment assembly includes a ferrule portion having a plurality of grooves receiving the end sections of optical fibers, wherein the grooves define the location and orientation of the end sections with respect to the ferrule portion. The assembly includes an integrated optical element for coupling the input/output of an optical fiber to the opto-electronic devices in the opto-electronic module. The optical element can be in the form of a structured reflective surface. The end of the optical fiber is at a defined distance to and aligned with the structured reflective surface. The structured reflective surfaces and the fiber alignment grooves can be formed by stamping.
