Patent number: 11745454Abstract: The present disclosure relates to methods of forming a fiber optic core, and a fiber optic component with a highly uniform cladding covering the fiber optic core. In one microfabrication process a first sacrificial tubing is provided which has a predetermined inner diameter. A quantity of a curable polymer is also provided. The first sacrificial tubing is at least partially filled with the curable polymer. The curable polymer is then cured. The first sacrificial tubing is then removed to produce a finished fiber optic core. Additional operations may be performed by which the fiber optic core is placed inside a thermoplastic tubing, which is itself placed inside a sacrificial heat shrink. Heat is applied to reflow the thermoplastic tubing around the fiber optic core, thus forming a highly uniform thickness cladding. When the sacrificial heat shrink tubing is removed a finished fiber optic component is present.Type: GrantFiled: May 4, 2021Date of Patent: September 5, 2023Assignee: Lawrence Livermore National Security, LLCInventors: Komal Kampasi, Razi-Ul Muhammad Haque, Michael Gregory Triplett

Patent number: 11691378Abstract: The present disclosure relates to a spatio-temporal stimulus responsive foldable structure. The structure may have a substrate having at least a region formed to provide engineered weakness to help facilitate bending or folding of the substrate about the region of engineered weakness. The substrate is formed to have a first shape. A stimulus responsive polymer (SRP) flexure is disposed at the region of engineered weakness. The SRP flexure is responsive to a predetermined stimulus actuation signal to bend or fold in response to exposure to the stimulus actuation signal, to cause the substrate to assume a second shape different from the first shape.Type: GrantFiled: August 16, 2021Date of Patent: July 4, 2023Assignee: Lawrence Livermore National Security, LLCInventors: Komal Kampasi, Eric B. Duoss, Razi-Ul Muhammad Haque
