Provided is a method for manufacturing an optical connector. The optical connector includes: an optical fiber including a glass fiber and a resin coating; and a ferrule including a through hole. The method for manufacturing includes: coating an inner wall of the through hole with a thermosetting resin; inserting the glass fiber exposed from the resin coating into the through hole; adjusting a mutual positional relationship between the optical fiber and the ferrule so that a distance between end surfaces of a tip of the glass fiber and a tip of the ferrule is equal to or less than 1 mm; rotationally aligning the glass fiber with respect to the ferrule; curing the thermosetting resin; and polishing the tip of the glass fiber and the tip of the ferrule.

This application relates generally to an optical fiber for the delivery of infrared light where the polarization state of the light entering the fiber is preserved upon exiting the fiber and the related methods for making thereof. The optical fiber has a wavelength between about 0.9 m and 15 m, comprises at least one infrared-transmitting glass, and has a polarization-maintaining (PM) transverse cross-sectional structure. The infrared-transmitting, polarization-maintaining (IR-PM) optical fiber has a birefringence greater than 10.sup.5 and has applications in dual-use technologies including laser power delivery, sensing and imaging.
