ABSTRACT:
A multi-lens apparatus for altering the mode field of an optical signal is disclosed. The apparatus includes an optical fiber having a core region defining an optical axis and a GRIN-fiber lens positioned in relation to one end of the optical fiber. A biconic lens including an external surface defined by two different curves disposed substantially orthogonal to one another, a major curve C1and a minor curve C2, with C1and C2intersecting at or near the optical axis is positioned in relation to an end of the GRIN-fiber lens remote from the fiber. A method of manufacturing a multi-lens apparatus for altering the mode field of an optical signal, and an optical assembly are also disclosed.
