Abstract: Methods of manufacturing multi-material fibers having one or more electrically-connectable devices disposed therein are described. In certain instances, the methods include the steps of: positioning the electrically-connectable device(s) within a corresponding pocket provided in a preform material; positioning a first electrical conductor longitudinally within a first conduit provided in the preform material; and drawing the multi-material fiber by causing the preform material to flow, such that the first electrical conductor extends within the multi-material fiber along a longitudinal axis thereof and makes an electrical contact with a first electrode located on each electrically-connectable device. A metallurgical bond may be formed between the first electrical conductor and the first electrode while drawing the multi-material fiber and/or, after drawing the multi-material fiber, the first electrical conductor may be located substantially along a neutral axis of the multi-material fiber.

Abstract: Radial fiber laser. The laser includes an optical fiber including a cavity containing a microfluidic gain medium bounded by a composite structure of alternating layers of high and low index materials forming an axially invariant, rotationally symmetric photonic bandgap cavity. The optical fiber also includes at least one microfluidic channel containing liquid crystal modulators in the fiber cladding extending in an axial direction and further includes a pair of electrodes flanking the microfluidic channel. An electrical potential across the pair of electrodes will rotate the liquid crystal molecules to rotate the linearly polarized state of light emitted from the cavity. An external linear polarizer is disposed around the fiber to modulate azimuthal laser intensity distribution.

Abstract: In one aspect, the disclosure features an article, including a fiber waveguide extending along a waveguide axis, the fiber waveguide including a core extending along the waveguide axis and a confinement region surrounding the core. The confinement region is configured to guide radiation at a first wavelength, λ 1 , along the waveguide axis and is configured to transmit at least some of the radiation at a second wavelength, λ 2 , incident on the confinement region along a path, where λ 1 and λ 2 are different. The core includes a core material selected to interact with radiation at λ 1 to produce radiation at λ 2 .
