“…Furthermore, inserting specifi c thickness deviations in particular layers of the refl ecting structure leads to the emergence of a radial resonant optical cavity fi bre [22][23][24][25] . We next discuss the consequences of co-drawing metals, semiconductors and insulators in the same fi bre to produce optoelectronic and thermal fi bre-based devices 23,[26][27][28][29] . Examples include thin-fi lm 27 and solid core 23,28 metal-semiconductor-metal (MSM) junctions that detect optical or thermal excitation.…”

“…For example, although a single photosensitive (or thermally sensitive) fi bre cannot determine the location of a point of excitation along its length, arranging a multiplicity of identical fi bres over a grid enables a point of optical (or thermal) excitation to be localized over the area of the grid. Th e detection of a point of optical or thermal excitation on an N × N grid normally requires the order of N 2 point detectors, but an array of linear 1D detectors produces the same capability with the order of N detectors only 23,26 (compare to traditional optical and thermal imaging systems described in, for example, refs 66,67).…”

Virtually all electronic and optoelectronic devices necessitate a challenging assembly of conducting, semiconducting and insulating materials into specific geometries with low-scattering interfaces and microscopic feature dimensions. A variety of wafer-based processing approaches have been developed to address these requirements, which although successful are at the same time inherently restricted by the wafer size, its planar geometry and the complexity associated with sequential high-precision processing steps. In contrast, optical-fibre drawing from a macroscopic preformed rod is simpler and yields extended lengths of uniform fibres. Recently, a new family of fibres composed of conductors, semiconductors and insulators has emerged. These fibres share the basic device attributes of their traditional electronic and optoelectronic counterparts, yet are fabricated using conventional preform-based fibre-processing methods, yielding kilometres of functional fibre devices. Two complementary approaches towards realizing sophisticated functions are explored: on the single-fibre level, the integration of a multiplicity of functional components into one fibre, and on the multiple-fibre level, the assembly of large-scale two- and three-dimensional geometric constructs made of many fibres. When applied together these two approaches pave the way to multifunctional fabric systems.

“…This is made possible by our recent success in fabricating a family of optoelectronic fibers [6], constructed from insulators, semiconductors, and metals, which are particularly suitable for our purpose by virtue of combining optical and electrical functionalities. Specifically, the class of fibers that we make use of in this paper is that of fibers constructed of a photoconductive glass [7] core contacted to metal electrodes that run along the length of the fiber [8], and is then surrounded by a protective, transparent polymer cladding [9] (see the inset of Fig. 2A).…”

The process of optical imaging and the use of a glass lens have been hitherto inseparable since it is the lens that is responsible for mapping incoming rays to form an image. While performing this critical role, the lens, by virtue of its geometry and materials composition, presents constraints on the size, weight, angular field of view, and environmental stability of an optical imaging system as a whole. Here, a new approach to optical imaging is presented. Tough polymeric light-sensing fibers are suspended on a frame to form large-scale, low-density, two-and three-dimensional photonic meshgrids. While a single grid can indeed locate a point of illumination, it is the stacking of a multiplicity of such grids, afforded by their essential transparency, which allows for the detection of the direction of illumination with a wide angular field of view. A surface-spanning-arrangement of such fibers is used to extract an arbitrary optical intensity distribution in a plane using a tomographic algorithm.Lensless imaging is achieved by a volumetric fiber assembly that extracts both the phase and intensity distributions of an incoming electromagnetic field, enabling one to readily determine the object from which the field originally emanated.The use of lenses for optical imaging has dominated optics since antiquity with no fundamental changes since, except for improvements in design and fabrication. The performance and size of any optical imaging system is usually determined by the quality and size of the lens(es) included in that system. The search for alternative approaches to optical imaging that do not rely on lenses, so-called lensless imaging, has had a venerable history. The common factor amongst all previous attempts is the introduction of a new optical system, usually an interferometer, which transforms the optical field before recording the intensity using a conventional opticaldetector array. A recent attempt demonstrated three-dimensional lensless imaging using a sophisticated interferometric arrangement and a novel computational algorithm [1]. In this paper we demonstrate a distinct, non-interferometric approach to lensless optical imaging that relies on a volumetric sampling of the electromagnetic field that is enabled by semitransparent 3D arrangements of photodetecting fibers.

Fibers are the building blocks of a broad spectrum of products from textiles to composites, and waveguides to wound dressings. While ubiquitous, the capabilities of fibers have not rapidly increased compared to semiconductor chip technology, for example. Recognizing that fibers lack the composition, geometry, and feature sizes for more functions, we set out years ago to explore the boundaries of fiber functionality. Our approach focused on a particular form of fiber production, thermal-drawing from a preform. This process has been used for producing single material fibers, but by combining metals, insulators, and semiconductors all within a single strand of fiber, an entire world of functionality in fibers has emerged. Fibers with optical, electrical, acoustic, or optoelectronic functionalities can be produced at scale from relatively easy-to-assemble macroscopic preforms. Two significant opportunities now present themselves. First, can we expect that fiber functions escalate in a predictable manner, creating the context for a "Moore's Law" analogue in fibers? Second, as fabrics occupy an enormous surface around our bodies, could fabrics offer valuable service to augment the human body? Towards answering these questions, we detail the materials, performance, and limitations of thermally-drawn fibers in different electronic applications and envision their potential in new fields.
