Abstract

A method for coupling a surface-oriented opto-electronic element, particularly, a VCSEL laser diode, an LED, or a photodiode, with an optical fiber and an opto-electronic element for carrying out such a method, the opto-electronic element having a rotationally symmetrical protruding structure disposed symmetrically with respect to the optically active zone of the opto-electronic element, includes the steps of wetting the butt of the fiber and/or the protruding structure of the opto-electronic element with a transparent adhesive, moving the opto-electronic element and/or the fiber toward each other such that a substantially frictionless movement of at least one of the element and fiber can occur, waiting for a self-centering of the fiber and the protruding portion; and waiting for or bringing about a hardening of the adhesive for purposes of fixing the now-centered configuration between the fiber and the protruding portion.
