IMPREGNABLE ABSORBENT MODULE BASED ON POLYMER COMPOSITE WITH SINGLE-WALL CARBON NANOTUBES (VERSIONS) Russian patent published in 2013 - IPC G02F1/01 H01S3/67 B82B1/00 

FIELD: physics.

SUBSTANCE: impregnable absorbent module based on a polymer composite with single-wall carbon nanotubes, made on single-mode optical fibre, having a core and cladding. The polymer composite contains a polymer which is mixed with single-wall carbon nanotubes, which is selected to absorb radiation with the required wavelength. A film of the composite with nanotubes is placed on a surface which is polished along one plane of the cladding of the fibre. According to the first version, the fibre is designed to transmit radiation in one direction; the impregnable absorbent module further contains a polariser which is made on a section of the single-mode fibre with cladding which is polished along said plane and lies before the polished section with the film made from the composite when radiation propagates in a given direction; the distance between the polariser and the absorbent enables deviation of the radiation polarisation vector by not more than 5 degrees. According to the second version, residual thickness of the fibre cladding ranges from 1 to 3 mcm; thickness of the film of the composite is not more than 1 mcm; said film is coated with an aluminium film with thickness of not more than 100 nm; the length of such a double-layer film ranges from 1 to 10 mm.

EFFECT: high optical stability of the absorbent.
