Abstract
An optical connector is provided. The optical connector includes an optical fiber and a ferrule mated with the optical fiber. The ferrule has a lens spaced from an end of the optical fiber. The lens is configured to focus an optical signal received from the optical fiber to converge to a beam waist before diverging thereafter.
Claims16
An optical connector, comprising:
- an optical fiber;
- and
- a ferrule mated with the optical fiber and having a lens spaced from an end of the optical fiber, the lens is configured to focus an optical signal received from the optical fiber to converge to a second beam waist before diverging thereafter, wherein the optical signal has a first beam waist at or immediately adjacent to the optical fiber, and wherein a diameter of the second beam waist is less than a beam diameter of the optical signal at the lens and is less than a diameter of the first beam waist.
An optical connector, comprising:
- a ferrule having a first lens and a second lens, the first lens is spaced from, and aligned with, a first optical fiber mated with the ferrule and the second lens is spaced from, and aligned with, a second optical fiber mated with the ferrule, the first lens has a different radius of curvature than the second lens, wherein the first lens is configured to focus a first optical signal received from the first optical fiber to converge to a beam waist before diverging thereafter, the second lens is configured to focus a second optical signal received from the second optical fiber to collimate.
An optical system, comprising:
- an optical connector having an optical fiber and a ferrule mated with the optical fiber, the ferrule having a lens spaced from an end of the optical fiber, the lens is configured to focus an optical signal received from the optical fiber to converge to a second beam waist, the optical signal has a first beam waist at or immediately adjacent to the optical fiber, and wherein a diameter of the second beam waist is less than a beam diameter of the optical signal at the lens and is less than a diameter of the first beam waist.
