Abstract
A lensed apparatus for altering the mode field of an optical signal is disclosed. The apparatus includes an optical fiber biconic lens disposed on an end of the optical fiber such that the optical fiber and the biconic lens define an optical axis. The biconic lens includes an external surface defined by two different curves disposed substantially orthogonal to one another, a major curve C1 and a minor curve C2, wherein C1 and C2 intersect at or near the optical axis. A method of manufacturing a lensed apparatus for altering the mode field of an optical signal, and an optical assembly are also disclosed.
Claims53
A lensed apparatus for altering the mode field of an optical signal, the apparatus comprising:
- an optical fiber;
- and
- a biconic lens disposed on an end of the optical fiber such that the optical fiber and the biconic lens define an optical axis, the biconic lens including an external surface defined by two different curves disposed substantially orthogonal to one another, a major curve C1 and a minor curve C2, wherein C1 and C2 intersect at or near the optical axis.
A method of manufacturing a lensed apparatus, the method comprising the steps of:
- disposing a biconic lens on one end of an optical fiber such that the optical fiber and biconic lens define an optical axis, the biconic lens comprising an external surface defined by two different curves disposed substantially orthogonal to one another, a major curve C1 and a minor curve C2, wherein C1 and C2 intersect at or near the optical axis.
An optical assembly comprising:
- an optical component;
- a substrate configured to support the component;
- and
- a lensed apparatus positioned on the substrate and in relation to the optical component to change the mode field of an optical signal passed between the lensed apparatus and the optical component, wherein the lensed apparatus includes an optical fiber and a biconic lens disposed on an end of the optical fiber such that the optical fiber and the biconic lens define an optical axis, the biconic lens including an external surface defined by two different curves disposed substantially orthogonal to one another, a major curve C1 and a minor curve C2, wherein C1 and C2 intersect at or near the optical axis.
