Fiber and Integrated Optics, 2008
Abstract This article presents a recent approach of polymer microtips integrated at the extremity of optical fibers by photopolymerization. The method is simple and flexible, and the obtained polymer/fiber hybrid system behaves as either a high quality microlens or a probe for near-field microscopy that requires strongly confined fields. Polymer-tipped

Polymer optical fiber amplifiers
2012 14th International Conference on Transparent Optical Networks (ICTON), 2012We develop Europium complexes and are now integrating them covalently into the polymer chains of PMMA. Monomer free polymer preforms are prepared, from which optical fibers are drawn. Our aim is to use these fibers as optical amplifiers at about 614 nm for in-house communication systems.

Studies of Polymer Optical Fibers
Organic Thin Films for Photonic Applications, 1995The growing demands in local area networks (LANs) for low cost broad band data communications are providing a major opportunity for further technology developments important to polymer optical materials and devices. Polymer optical fibers (POF) can satisfy requirements for high-bandwidth, quick-connect, fiber optics for short distance (100 m) data ...

Fiber optic polymer cure sensor
Journal of Lightwave Technology, 1988An in situ method is presented for monitoring the curing of polymeric compositions, including epoxy- and polymide-based composites. The sensor measures the difference between the refractive index of the cured and uncured composition, with the index increasing as polymerization proceeds.

In previous chapters, different optical sensing mechanisms have been discussed. The characteristics of the different types of OFSs have been presented and compared. Although different types and characteristics have been shown, all those sensing techniques were fabricated using silica optical fibers. In this chapter, an alternative line of optical fiber

Polymer Optical Fiber Couplers
SAE Technical Paper Series, 1992<div class="htmlview paragraph">With increasing electronic function and sophistication in automobiles, optical fibers provide an attractive alternative to copper based media. Lower labor and component costs make polymer optical fibers (POF) preferable for this application to fibers based on silica.

Polymer optical fiber amplifier
Applied Physics Letters, 1993Polymer optical fiber amplifiers (POFA) of graded-index (GI) type, which have a gain in visible region, were successfully prepared by the interfacial-gel polymerization technique. The gain of 27 dB was observed at 591 nm signal wavelength with 690 W launched pump power at 532 nm in a GI POFA with 0.5 m length.

Polymer optical fibers for mechanical wave monitoring
Optics Letters, 2020This Letter presents the development of a low-cost polymer optical fiber (POF) sensor for mechanical wave monitoring. The POF is fabricated using the light polymerization spinning process (LPS-POF) with Bisphenol-A as its main component, resulting in a highly flexible fiber. The proposed LPS-POF sensor is applied on the assessment of squared waves with

All-optical devices in polymer optical fiber
Chemical Physics, 1999Abstract We report on polymer optical fiber devices for sensors, optical switches/logic, and optical actuators. In this paper, we give a brief overview of polymer fibers, discuss recent all-optical switching results, and describe how an optical sensor and actuator can be built into a single fiber device.
