Abstract
The present invention relates to ultrafast laser inscribed structures for signal concentration in focal plan arrays, focal plan arrays, imaging and/or sensing apparatuses comprising said focal plan arrays, as well as methods of making and/or using ultrafast laser inscribed structures for signal concentration in focal plan arrays, focal plan arrays, imaging and/or sensing apparatuses comprising said focal plan arrays. Such ultrafast laser inscribed structures are particularly adapted to condense broad band radiation, thus allowing increased sensing efficiencies to be obtained from imaging and/or sensing apparatuses. Such ultrafast laser inscribed structures can be efficiently produced by the processes provided herein.
Claims16
An ultrafast laser inscribed structure comprising a substrate, said substrate comprising:
- a) a material selected from:
- (i) a unary, binary, ternary, or quaternary a non-glass, crystalline material;
- (ii) an amorphous material;
- and/or
- (iii) a ceramic;
- b) a plurality of two and/or three dimensional condensed structures, each of said plurality of two and/or three dimensional condensed structures being derived from the substrate material adjacent to said condensed structure
- c) said substrate comprises elements selected from the following periodic table groups:
- II and VI;
- III and V;
- IV and VI;
- VI;
- II and V and J, III, VI;
- d) said amorphous material comprises a polymer, silicate glass, borate glass, phosphate glass, heavy metal oxide glass, halide glass, chalcogenide glass;
- and
- e) each of said plurality condensing structures comprising a structurally modified, oxidized or alloyed derivative of said adjacent substrate material.
