Method and system for aligning and positioning an optical fiber and microlens array

A method of aligning an optical fiber array, the method comprising:

• providing a plurality of optical fibers, wherein the plurality of optical fibers comprises:
• a first optical fiber having a first end and a second end;
• and
• a second optical fiber having a third end and a fourth end;
• positioning the first optical fiber such that the first end of the optical fiber faces an MLA alignment system, wherein, the MLA alignment system comprises:
• a tilt sensing device;
• and
• a position sensing device;
• providing a microlens array (MLA) having a plurality of lenslets in a first MLA position between the first end of the first optical fiber and the MLA alignment system, wherein the plurality of lenslets comprises a first lenslet and a second lenslet;
• adjusting the first end of the first optical fiber into coarse alignment with the first lenslet of the plurality of lenslets;
• generating a first MLA beam output for the first optical fiber, wherein the first MLA beam output comprises at least one of a first MLA tilt value or a first MLA position value;
• comparing the first MLA beam output with an alignment threshold, wherein the alignment threshold comprises at least one of an MLA tilt threshold or an MLA position threshold;
• attaching the first end of the first optical fiber to a surface of the first lenslet;
• and
• moving the MLA to a second MLA position between the third end of the second optical fiber and the MLA alignment system such that the third end of the second optical fiber is in coarse alignment with the second lenslet.
