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.

Coupling in a twin-core microstructured polymer optical fiber

Applied Physics Letters, 2004
Theoretical calculations and experimental results are reported for a microstructured polymer optical fiber twin-core coupler. Beat lengths are calculated using a fully vectorial, Fourier decomposition method, which show that the beat length is extremely sensitive to any core asymmetry. Reasonably good agreement between theory and experiment is obtained.

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

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 ...

Polymer optical microstructured fiber with birefringence induced by stress-applying elements

Optics Letters, 2014
We report on the fabrication of a birefringent microstructured PMMA fiber with polystyrene stress-applying elements located in the solid part of the cladding. A microstructured part of the cladding composed of three rings of holes was made of a technical-grade PMMA by a drilling method.

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.

Sensitivity of Birefringent Microstructured Polymer Optical Fiber to Hydrostatic Pressure

IEEE Photonics Technology Letters, 2013
We present a PMMA birefringent fiber with enhanced polarimetric sensitivity to hydrostatic pressure, obtained by enlarging selected holes in the microstructured cladding. The fiber shows a linear response to pressure with small hysteresis in the pressure range up to 8.5 MPa and the sensitivity of 48 ${\rm rad}/{\rm MPa}\cdot{\rm m}$ at 600 nm.

Microstructured Polymer Optical Fiber Biosensors for Detection of DNA and Antibodies

Optical Fiber Sensors, 2006
We demonstrate selective detection of fluorescently labeled single stranded DNA molecules from aqueous solutions using a Microstructured Polymer Optical Fiber. Furthermore, we present results on indirect label-free detection of antibodies by labeling a probe molecule.

Low Loss and Temperature Stable Microstructured Polymer Optical Fibers

Journal of Lightwave Technology, 2012
We report on a study of the loss mechanisms in microstructured polymer optical fibers (mPOF), resulting in the fabrication of mPOF with a loss equal to that of commercial polymer optical fibers of 0.16 dB/m at 650 nm, nearing the limit imposed by material absorption.
