Abstract
Abstract Disclosed is an optical package including at least one electro-optical component aligned with at least one optical fiber. The electro-optical component is mounted on a surface which is essentially parallel to, but not coplanar with, the longitudinal axis of the fiber and light is coupled between the fiber and component by bending the light path. Electrical connection to the component is provided by conductors mounted over the same surface, thus producing a compact package. The invention is used preferably with arrays of components and fibers to eliminate the need for a vertical fanout to contact the components.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
77 words
An optical component package comprising: at least one optical fiber having a longitudinal axis and mounted within a block, which block and fiber have coplanar beveled edges; a reflective layer formed on the beveled edges of the block and fiber; and at least one electro-optical component aligned with said edges so that light is reflected between the component and fiber, said component mounted over a surface which is essentially parallel to the longitudinal axis of the fiber.
Claim 2
Dependent Claim
77 words
An optical component package comprising: at least one optical fiber having a longitudinal axis and mounted within a block, which block and fiber have coplanar beveled edges; a reflective layer formed on the beveled edges of the block and fiber; and at least one electro-optical component aligned with said edges so that light is reflected between the component and fiber, said component mounted over a surface which is essentially parallel to the longitudinal axis of the fiber.
Claim 3
Dependent Claim
24 words
The device according to claim 1 further comprising means for providing electrical connection to the component mounted over the same surface as the component.
Claim 4
Dependent Claim
26 words
The device according to claim 2 wherein the component and means for providing electrical connection to the component are mounted over one surface of the block.
Claim 5
Dependent Claim
30 words
The device according to claim 2 wherein the component and means for providing electrical connection to the component are mounted on the surface of a body separate from the block.
Claim 6
Dependent Claim
13 words
The device according to claim 3 wherein the component is a photoresponsive device.
Claim 7
Dependent Claim
21 words
The device according to claim 4 wherein the component is a light-emitting device and the separate body is a heat sink.
Claim 8
Dependent Claim
46 words
The device according to claim 1 wherein one surface of the block is polished at a small angle to the fiber axis so that one end of the fiber in the block is exposed where the light will be coupled between the component and the fiber.
Claim 9
Dependent Claim
23 words
The device according to claim 1 wherein the component, the reflective layer and a portion of the fiber are encapsulated within a material.
Claim 10
Dependent Claim
90 words
An optical component package comprising: an array of optical fibers mounted essentially in a single plane within a semiconductor block, each fiber having a longitudinal axis and each fiber and the block having coplanar beveled edges; a reflective layer formed on the beveled edges; an array of electro-optical components aligned with said edges and, mounted on a surface which is essentially parallel to but not coplanar with the longitudinal axes of the fibers; and means for providing electrical connection to the components mounted over the same surface as the components.
Claim 11
Dependent Claim
90 words
An optical component package comprising: an array of optical fibers mounted essentially in a single plane within a semiconductor block, each fiber having a longitudinal axis and each fiber and the block having coplanar beveled edges; a reflective layer formed on the beveled edges; an array of electro-optical components aligned with said edges and, mounted on a surface which is essentially parallel to but not coplanar with the longitudinal axes of the fibers; and means for providing electrical connection to the components mounted over the same surface as the components.
Claim 12
Dependent Claim
26 words
A package according to claim 9 wherein the means for providing electrical connection comprises a fanout array of conductors formed over the surface of the block.
