Abstract

The present invention includes a radiation collector configured to collect incident radiation. The radiation collector includes a radiation directing component configured to redirect the incident radiation, a buffer component configured to receive the radiation redirected by the radiation directing component, and a propagation component configured to receive the radiation from the buffer component and to propagate the radiation towards a first end of the propagation component.

Claims

1. A method of collecting incident radiation, the method comprising:

receiving the incident radiation from at least a first direction;

redirecting the incident radiation with a radiation directing component into a propagation component, the radiation directing component being coupled to a buffer component configured to optically separate radiation directing component and propagation component and to retain the incident radiation in the propagation component;

retaining the radiation in the propagation component such that the radiation is propagated generally toward a first end of the propagation component; and

optically separating the radiation component from the propagation component such that the radiation propagating with the propagation component is prevented from interacting with the radiation directing component.

2. The method of claim 1, wherein the radiation is retained within the propagation component by at least total internal reflection.

3. The method of claim 2, wherein the propagation component includes a reflection coating on at least a first surface and the radiation is retained within the propagation component by at least reflection from the reflection coating.

4. The method of claim 1, further comprising coupling the radiation propagated toward the first end of the propagation component to an output component, the output component selected from the group consisting of an energy converting component, a collector, and an optical transport component.

5. A method of coupling optical radiation from at least a first source of optical radiation into a first optical transport component including a first propagation component and a first buffer component, the first buffer component radially overlaying the first propagation component and the first optical transport component configured to propagate optical radiation in generally a first direction toward a first end of the first optical transport component or in generally a second direction toward a second end of the first optical transport component, the method comprising:

positioning the at least first source of optical radiation adjacent an exterior radial surface of the first buffer component; and

directing at least a portion of the radiation emanating from the source of optical radiation into the first buffer component of the first optical transport component such that the radiation is coupled into the first propagation component and is propagated within the first propagation component toward at least one of the first end or the second end of the first propagation component due at least to total internal reflection between the first propagation component and the second component.

6. The method of claim 5, wherein the source of optical radiation is selected from the group consisting of a laser, a laser diode, a light emitting diode, or a second optical transport component.

7. The method of claim 5, wherein the optical radiation is directed toward the first end of the first propagation component due to the optical radiation having a wavelength corresponding to a first wavelength.

8. The method of claim 7, wherein the optical radiation is directed toward the second end of the first propagation component due to the optical radiation having a wavelength corresponding to a second wavelength.

9. An optical connector for transferring radiation, the optical connector comprising:

a first optical transport component including a first propagation component and a first buffer component, the first buffer component radially overlaying the first propagation component, the first optical transport component configured to propagate optical radiation in generally a first direction toward a first end of the first optical transport component;

a second optical transport component including a second propagation component and a second buffer component, the second buffer component radially overlaying the second propagation component, the second optical transport component configured to propagate optical radiation in generally a second direction toward a second end of the second optical transport component, the second optical transport component being positioned such that the second direction is not parallel to the first direction; and

a radiation directing component located proximate to the first end of the first optical transport component and proximate to an exterior surface of the buffer component of the second optical transport component, the radiation directing component configured to redirect the optical radiation propagating generally in the first direction through the exterior surface of the second optical transport into the second propagation component such that the optical radiation is propagated within second optical transport component generally along the second direction of the second optical transport component.

10. The optical connector of claim 9, wherein the radiation directing component is coupled to the exterior surface of the second buffer component.

11. The optical connector of claim 10, wherein the radiation directing component includes a holographic element.

12. The optical connector of claim 10, wherein the radiation directing component includes a diffraction grating.

13. The optical connector of claim 9, wherein the radiation directing component is configured to redirect the optical radiation such that the optical radiation will propagate within the second optical transport component in the second direction when a wavelength of the optical radiation is a first wavelength and is further configured to redirect the optical radiation such that the optical radiation will propagate within the second optical transport component in a third direction generally opposite to the second direction when the wavelength of the optical radiation is a second wavelength different than the first wavelength.

14. The optical connector of claim 10, wherein the optical radiation coupled from the first optical transport component into the second optical transport component includes a data signal.
