Significant noise reduction in multimode Fiber links using graded-index Plastic Optical Fiber with microscopic heterogeneous core
39th European Conference and Exhibition on Optical Communication (ECOC 2013), 2013Co-Authors: Azusa Inoue, Rei Furukawa, Motoharu Matsuura, Y. KoikeAbstract:We show that the reflection noises in multimode Fiber links can be significantly reduced by using graded-index Plastic Optical Fiber with microscopic heterogeneous core. It is suggested that the intrinsic mode coupling due to the microscopic heterogeneities can result in the noise reduction without Optical isolator and Fiber end-face polishing.

the future of Plastic Optical Fiber
Npg Asia Materials, 2009Co-Authors: Y. Koike, Makoto AsaiAbstract:The number of services providing large-volume information content, such as high-definition movies, continues to increase rapidly. Single-mode glass Optical Fiber (SM GOF), which has been widely deployed in data trunk lines and pipelines connecting large cities and nations, has already become indispensable as an information transmission medium. However, SM GOF is mechanically weak and lacks sufficient bending ability. Moreover, as the core diameter is very small, just 10 μm, extremely precise techniques and expensive devices are required to connect Fibers to signal receiving devices. It is therefore difficult to lay SM GOF for very short reach networks, such as local area networks in buildings. These difficulties are recognized as the problem of the ‘last hundred meters’ for Optical Fiber infrastructure. Plastic Optical Fiber (POF) has a relatively large-diameter core and is flexible enough to be laid down for network infrastructure in the last hundred meters. However, POF has two important weaknesses: it has significantly lower bandwidth than GOF, and its attenuation is far higher. Recent developments conquering both of these issues now mean that POF is regarded as the strongest candidate at present for Optical data transmission over the last hundred meters. Here we review the status of POF development and research, particularly with respect to the application of ‘photonics polymer’.

High-Bandwidth Plastic Optical Fiber for Fiber to the Display
Journal of Lightwave Technology, 2006Co-Authors: Y. Koike, Takaaki IshigureAbstract:Novel photonics polymer devices for broadband technologies are described, focusing on the high-bandwidth graded-index Plastic Optical Fiber (GI POF). Based on these photonics polymer device technologies, the concept of "Fiber to the Display" is proposed, where GI POF is directly distributed to display from main server in a building or house. Therefore, real-time face-to-face communication with high-definition-television quality becomes possible, which cannot be achieved by current technologies. The authors believe that new innovative concepts of broadband society in the 21st century will be realized by "the proposal from the material side."

High-bandwidth Plastic Optical Fiber with W-refractive index profile
IEEE Photonics Technology Letters, 2004Co-Authors: Takaaki Ishigure, H. Endo, K. Ohdoko, Y. KoikeAbstract:A Plastic Optical Fiber having a W-shaped refractive index profile [W-shaped Plastic Optical Fiber (POF)] was prepared for the first time to realize a higher bit rate transmission than those of the conventional silica-based multimode Fiber and graded-index (GI) POF links. Since the W-shaped POF has a valley of the refractive index at the boundary of the core and cladding of the conventional GI POF, the group delay of higher order modes is strongly influenced, thus compensating the modal dispersion that exists in the GI POF. The modal dispersion compensation effect by the W-shaped index profile was theoretically and experimentally confirmed.
