Abstract:
A method of coupling an element with a fiber, which comprises:providing an optical fiber having a fiber rotational axis and a fiber butt; providing a surface-oriented opto-electronic element having: an optically active zone; a rotational axis; and a rotationally symmetric protruding structure symmetrically disposed with respect to the optically active zone; wetting at least one of the fiber butt and the protruding structure with a transparent adhesive; moving the element and the optical fiber toward each other to spread the adhesive therebetween; disposing at least one of the element and the fiber to enable a substantially frictionless movement of the fiber perpendicular to the rotational axis of the element and perpendicular to the fiber rotational axis; waiting for the fiber and the protruding portion to self-center; and one of waiting for and bringing about a hardening of the adhesive to fix the now-centered configuration between the fiber and the protruding portion.
