A method of making a waveguiding optical component includes processing a polymer optical material to form a billet having an axis of light transmission and having residual stress maintaining a transverse extent of the billet; placing the billet into a mold, the mold being configured to constrain transverse expansion of the billet according to a desired shape of the waveguiding optical component; and heating the billet in the mold to induce relaxation of the residual stress and corresponding transverse expansion of the billet, thereby forming the billet into the waveguiding optical component with the desired shape. An alternative method begins with a collection of individual canes or fiber segments which are fused during the heating process, bypassing a separate process of forming a billet.

A method of making a transverse Anderson localization (TAL) element includes mixing pellets together to make a mixture, the pellets being of two or more distinct materials having respective wave speeds effective to provide Anderson guiding. The mixture is fused to make a preform which has respective pellet-size areas of the distinct materials corresponding to the pellets in the mixture. One or more stretching operations is performed to stretch the preform into the TAL element.

Pellet-start process for making transverse anderson localization optical element

A wave guide face plate for transmitting an image formed in a scintillating material included as part of a transmitting medium is disclosed. The transmitting medium includes a random distribution of different refractive index regions in two orthogonal dimensions, and an essentially consistent refractive index in a third orthogonal dimension. The third orthogonal direction is aligned with a transmission axis of the wave transmitter extending from an input location to a wave detector location. The transmission efficiency of the wave guide faceplate is improved in situations where the entry angle of the input radiation is different from the axis of the wave transmitter as compared to conventional faceplates.

Wave guiding element and method of manufacture

A system and method for drawing a preform. A draw tower includes a mount configured to suspend a preform. The method includes securing the preform to a mount and enclosing the preform in an enclosure. The enclosure has an external surface and defines an orifice through which material drawn from the preform can exit the enclosure. The preform is heated through the external surface is heated to a temperature suitable for drawing the material from the preform. Material is drawn from the preform through the orifice and collected.

Enclosed drawing method

Millimeter to nano-scale structures manufactured using a multi-component polymer fiber matrix are disclosed. The use of dissimilar polymers allows the selective dissolution of the polymers at various stages of the manufacturing process. In one application, biocompatible matrixes may be formed with long pore length and small pore size. The manufacturing process begins with a first polymer fiber arranged in a matrix formed by a second polymer fiber. End caps may be attached to provide structural support and the polymer fiber matrix selectively dissolved away leaving only the long polymer fibers. These may be exposed to another product, such as a biocompatible gel to form a biocompatible matrix. The polymer fibers may then be selectively dissolved leaving only a biocompatible gel scaffold with the pores formed by the dissolved polymer fibers.

High aspect ratio template and method for producing same

An endoscopic shaft having multiple endoscopic elements set in a polymer common housing. The endoscopic elements may be drawn with the common housing to manufacture a component, called an EndoFiber, which forms the length of the endoscopic shaft. A second structure, called an Endocap, may be provided that includes optical elements and which is attached to the end of the EndoFiber to form the shaft.

Polymer endoscopic shaft

A method to fabricate solid linear fiber arrays, multi-hole arrays and inverse multi-hole arrays (i.e. space-separated arrays). These arrays may be used for example as capillary arrays, photonic crystal fiber, tissues engineering scaffolds and templates, imaging guides, thermal photovoltaic device, and thermal electric devices. The number of fibers used to fabricate the structures is variable. Individual fibers are deposited into a fiber depository and made to bond together. The deposition may be performed in line with fiber production or may be performed after producing the fibers through fiber rewinding. The bonded linear fiber array may be removed from the fiber depositories.
