APPARATUS FOR THE COLLECTION AND TRANSMISSION OF ELECTROMAGNETIC RADIATION

摘要

A collector for propagating incident radiation is disclosed. The collector may comprise a light directing component coupled to a buffer component, a first propagation component coupled to the buffer component and configured to transmit the incident radiation into a collector region through one of a plurality of windows, and an optical transport assembly coupled to an end of the collector region and having a second propagation component. Each light directing component may be configured to redirect the incident radiation from a first direction to a second direction, and the collector region may include a plurality of regions exhibiting a refractive index value that gradually transitions from about 1.5 to about 2.0. The second propagation component may be further configured to retain the incident radiation.

1. A propagation apparatus for electromagnetic radiation, the propagation apparatus comprising
a first plurality of regions each having a first index of refraction; and a second plurality of spaced apart regions interleaved with the first plurality of regions, an index of refraction of each of the second plurality of spaced apart regions generally increases from the first index of refraction at a leading edge of the spaced apart region to a peak value and then decreases towards the first index of refraction at a trailing edge of the spaced apart region, wherein the electromagnetic radiation traverses generally in a first direction through a first region of the first plurality of regions, followed by a first region of the second plurality of spaced apart regions, followed by a second region of the first plurality of regions, and followed by a second region of the second plurality of spaced apart regions.
