Assembly and method for cleaving a glass body with a laser

A method of manufacturing an optical fiber having a transmitting portion and an end cap with a face at a desired angle greater than 0 degrees and with reduced light-scattering or absorbing detriments with a cleaving assembly, the cleaving assembly including a laser device for emitting a laser beam, a rotating device having a head, and a positioning fixture, said method comprising:

• providing the transmitting portion extending between a first end and a second end and having a diameter of at least 125 μm;
• providing the end cap formed of a glass material extending between a terminal end to be cleaved at the desired angle and a mounting end, the end cap having a diameter and having an initial length;
• securing the first end of the transmitting portion to the mounting end of the end cap;
• positioning the rotating device and the positioning fixture centrally aligned along a central axis that is orthogonal to the laser beam;
• mounting the positioning fixture to the head of the rotating device;
• supporting the transmitting portion along a tapered surface of the positioning fixture, so that the transmitting portion and the end cap extends transverse to the central axis at a predetermined angle;
• and
• rotating the positioning fixture and the head of the rotating device about the central axis such that the laser beam cleaves the terminal end of the end cap at a desired angle corresponding to the predetermined angle and at a final desired length.

A method of manufacturing fiber end caps with a face at a desired angle greater than 0 degrees and with reduced light-scattering or absorbing detriments with a cleaving assembly, the cleaving assembly including a laser device for emitting a laser beam, a rotating device having a head, and a positioning fixture, said method comprising:

• providing a support rod extending between a first end and a second end and having a diameter of at least 125 μm;
• providing an end cap formed of a glass material extending between a terminal end to be cleaved at a desired angle and a final desired length and a mounting end;
• securing the first end of the support rod to the mounting end of the end cap to form a temporary glass body;
• positioning the rotating device and the positioning fixture centrally aligned along a central axis that is orthogonal to the laser beam;
• mounting the positioning fixture to the head of the rotating device;
• supporting the temporary glass body so that the temporary glass body extends along a tapered surface of the positioning fixture and the end cap extends transverse to the central axis at the desired angle;
• rotating the positioning fixture and the head of the rotating device about the central axis while the temporary glass body is supported such that the laser beam cleaves the terminal end of the end cap at the desired angle and the final desired length;
• and
• removing the end cap from the support rod to dissemble the temporary glass body and finishing the mounting end of the end cap to achieve an acceptable surface thereon.
