Abstract

The present invention provides a mega-boule for use in fabricating microchannel plates (MCPs). The mega-boule includes a cross-sectional surface having at least first, second and third areas, each area occupying a distinct portion of the cross-sectional surface. The first and second areas include a plurality of optical fibers, transversely oriented to the cross-sectional surface, each optical fiber having a cladding formed of non-etchable material and a core formed of etchable material. The third area is disposed interstitially between and surrounding the first and second areas, and includes non-etchable material.

Claims (36)

1. A mega-boule for use in fabricating microchannel plates (MCPs), the mega-boule comprising

a cross-sectional surface including at least first, second and third areas, each area occupying a distinct portion of the cross-sectional surface;

the first and second areas including a plurality of optical fibers, transversely oriented to the cross-sectional surface, each optical fiber having a cladding formed of non-etchable material and a core formed of etchable material; and

the third area disposed interstitially between and surrounding the first and second areas, the third area formed of non-etchable optical material.

2. The mega-boule of claim 1 wherein

the third area includes a plurality of support rods transversely oriented to the cross-sectional surface, and

the plurality of optical fibers in the first and second areas and the plurality of support rods in the third area intersect and pass through the cross-sectional surface.

3. The mega-boule of claim 2 further including

at least a fourth area, occupying another distinct portion of the cross-sectional surface;

the fourth area including another plurality of optical fibers of similar materials of the optical fibers of the first and second areas; and

the third area disposed interstitially between and surrounding the first, second and fourth areas.

4. The mega-boule of claim 2 wherein

the echable material of the first and second areas and the non-etchable material of the first, second and third areas are glass, and

the non-etchable material includes a higher lead content than the etchable material.

5. The mega-boule of claim 2 wherein

the non-etchable optical material of the third area includes a plurality of support rods transversely oriented to the cross-sectional surface, and

the optical fibers of the first area and a portion of the plurality of support rods are configured for use as an MCP.

6. The mega-boule of claim 5 wherein the plurality of optical fibers and the plurality of support rods form a fused monolithic stack, when heated and pressed.

7. The mega-boule of claim 2 wherein

the plurality of optical fibers of the first and second areas form transverse microchannels in cores of the plurality of optical fibers, when the cores are etched.

8. The mega-boule of claim 2 wherein

the first and second areas each forms a rectangular geometry.

9. The mega-boule of claim 2 wherein

the cross-sectional surface is of a predetermined area, and

the predetermined area is based on accommodating semiconductor wafer fabrication tools.

10. The mega-boule of claim 2 wherein

the first and second areas each includes a size corresponding to a size of an active region of an MCP configured as an amplifier for an image intensifier tube.

11. The mega-boule of claim 2 wherein

each support rod of the plurality of support rods includes an optical fiber.

12. The mega-boule of claim 2 wherein

each support rod of the plurality of support rods includes an optical fiber having a cladding formed of non-etchable material and a core formed of non-etchable material.

13. The mega-boule of claim 2 wherein

the first and second areas each forms a circular geometry.

14. The mega-boule of claim 1 wherein

the non-etchable optical material of the third area includes a plurality of support rods transversely oriented to the cross-sectional surface, and

an optical fiber of the plurality of optical fibers and a support rod of the plurality of support rods have a cross-sectional area similar to each other.
