Fabrication Conditions for Randomly Microstructured Polymer Optical Fibers

Integrated Photonics Research and Applications/Nanophotonics, 2006
Microstructured polymer optical fiber was fabricated in which bubbles were randomly distributed in the cladding to both guide and scatter light. The effect of fabrication conditions on the fiber structure and properties is discussed.

Sensing characteristics of birefringent microstructured polymer optical fiber

SPIE Proceedings, 2011
We experimentally studied several sensing characteristics of a birefringent microstructured polymer optical fiber. The fiber exhibits a birefringence of the order 2×10 -5 at 1.3 μm because of two small holes adjacent to the core. In this fiber, we measured spectral dependence of phase and group modal birefringence, bending losses, polarimetric ...

Tunable attenuator based on polymer microstructured optical fibers

Optoelectronics Letters, 2007
Based on polymer microstructured optical fibers (PMOF) and selective liquid crystal injection technology, a novel temperature control tunable attenuator is designed theoretically in this paper. In our experiments, PMMA microstructured optical fibers with high performance are drawn successfully and the selective injection of liquid crystal 5CB into ...

Laser based microstructuring of polymer optical fibers for sensors optimization

SPIE Proceedings, 2015
Microstructuring of Polymer Optical Fibers-POF through surface modification with UV excimer laser radiation has been performed and studied. The laser modified surface cavities on fibers act as material receptors of exact volume allowing highly controllable and repeatable structures.

Transmission of terahertz radiation using a microstructured polymer optical fiber

Optics Letters, 2008
A hollow-core microstructured polymer optical fiber was analyzed in the terahertz (THz) region. Spectral analysis of time domain data shows propagation of THz waves in both the hollow-core and the microstructured cladding with a time delay of approximately 20 ps. The frequency range and shift of the transmission bands between different sized waveguides

Mass-fabrication of air-core microstructured polymer optical fiber

2008 Conference on Lasers and Electro-Optics, 2008
An air-core, 252 holes cladding, 51% air-occupied fraction PMMA-based MPOF as successfully fabricated by drawing an extruded 253 holes preform. With the extrusion technique, air-core MPOF preform could be produced on a large scale.

High birefringent microstructured polymer optical fiber with frozen stresses

12th Conference on Integrated Optics: Sensors, Sensing Structures, and Methods, 2017
We report on fabrication of a new type high birefringent microstructured polymer fiber with a PMMA stress applied element in the core. An inner part of preform consists regular three rings of holes, made by drilling method. Inside the microstructure we drilled an additional hole, where a special type – strongly stressed PMMA rod was placed.

Microstructured polymer optical fibers and its application in sensing

2015 International Conference on Electrical, Electronics, Signals, Communication and Optimization (EESCO), 2015
Here a microstructured polymer optical fiber is manufactured using suitable polymer material TOPAS , in order to maintain the refractive index contrast to that of the host material and there by reducing the losses. Bragg gratings were inscribed in the core of the microstructured fiber considering the dispersion loss, scattering and shadowing effect due

Hybrid active polymer/silica microstructured photonic crystal optical fibers

MRS Proceedings, 2001
AbstractWe review several applications of microstructured photonic crystal optical fibers that incorporate active materials infused into the air-holes. The tunable optical characteristics of the materials combined with the unique structure of the fiber enable a number of functionalities including reconfigurability and tunability for various fiber ...

Multigigabit short-reach communication over microstructured polymer optical fiber

Optical Fiber Technology, 2017
Abstract In contrast to conventional polymer optical fibers (POF) microstructured POF (mPOF) provide an additional opportunity to control the optical properties of the propagating signals. A particular arrangement of the air holes allows to reduce the number of waveguide modes and thus overcome the bandwidth limitation which is inherent for step ...
