Optical fiber structure and optical fiber array structure

Abstract

An optical fiber structure, includes a substrate, provided with a holding slot; an optical fiber cable, partially arranged in the holding slot; and an isolator, comprising a positioning structure arranged in the holding slot and aligned with an end surface of the optical fiber cable. The present disclosure can not only improve the optical coupling accuracy but also make the optical fiber structure more compact by pasting the isolator in the holding slot and directly aligning with the end surface of the optical fiber cable, which provides a basis for the product to be miniaturized and integrated. The isolator includes a positioning structure, and the isolator has a unidirectional transmission characteristic, therefore, the positioning structure greatly reduces the assembly difficulty and improves the assembly efficiency.
