In this work, we report the fabrication of an all-polymer multimaterial optical fiber based on two different grades cyclo-olefin polymers (known as Zeonex) and high-performance thermoplastic polysulfone (PSU) with glass transition temperature (Tg) 189°C. The core/cladding structure using Zeonex (E48R/480R, respectively) was developed a co-extrusion method followed by rod-in-tube approach...

Dielectric-loaded surface plasmon polariton waveguides (DLSPPWs) are typically made using nanolithography fabrication methods. In this paper we demonstrate that near-field electrospinning of polymer nanofibers directly onto a gold coated substrate can be used as an alternative method for rapid prototype fabrication of DLSPPWs. Surface plasmon polaritons (SPPs) have been excited directly inside ...

Advancements in fabrication of miniaturized optical scanners would benefit from micrometer sized fiber tips. The change the cross section an tip is often accompanied with presence a longer tapered area. reduction double clad fibers (DCFs) flat interface surface at region where takes place (with abrupt section) considered this paper.

0.5% Holmium (Ho) doped YAG single crystal fiber (SCF) was fabricated using Laser Heated Pedestal Growth (LHPG) method and characterized for its optical absorption and emission properties involving transitions between the 5I8 and 5I7 energy levels. The results verified the absorption peaks suitable for in-band direct pumping at 1908 nm and 1932 nm with the emission occurring between 2050 and 21...

This paper describes the design and fabrication of fiber-optic nanoprobes developed for optical detection in single living cells. It is critical to fabricate probes with well-controlled nanoapertures for optimized spatial resolution and optical transmission. The detection sensitivity of fiber-optic nanoprobe depends mainly on the extremely small excitation volume that is determined by the apert...

Molecular imprinting is earning worldwide attention from researchers in the field of sensing and diagnostic applications, due to its properties of inevitable specific affinity for the template molecule. The fabrication of complementary template imprints allows this technique to achieve high selectivity for the analyte to be sensed. Sensors incorporating this technique along with surface plasmon...
