Patterning method using imprint mold, pattern structure fabricated by the method, and imprinting system

A patterning method using an imprint mold, to form an imprinted pattern structure, includes providing a resist layer from which the pattern structure will be formed, performing a first imprint process on a first area of the resist layer by using the imprint mold to form a first pattern of the pattern structure through deformation of the resist layer in the first area, and performing a second imprint process on a second area of the resist layer by using the imprint mold to form a second pattern of the pattern structure through deformation of the resist layer in the second area. The first and second areas are overlapped with each other in a third area of the resist layer, and the performing the second imprint process deforms a first portion of the first pattern in the third area to form the second pattern.

BORON NITRIDE NANOTUBE COATED OPTICAL WAVEGUIDE AND USES THEREOF

A solution is provided comprising boron nitride nanotubes (BNNTs) in a liquid solvent. An optical waveguide, such as an optical fiber, is contacted with the solution so as to form a layer of the solution supported on at least a portion of the optical waveguide. The liquid solvent is then removed from the layer of the solution supported on the optical waveguide in order to form a coating of the BNNTs on the optical waveguide. Further provided is a BNNT coated optical waveguide for use as a sensor.
