“…It has been reported that the data transmission rate required for the high-definition multimedia interface (HDMI) standard (10 Gbps) has been achieved in a system using the double cladding GI POF, even when knotted ten times (Figure 8). Novel POFs with other structures, such as multiple GI cores, are being investigated vigorously all over the world [58].…”

T he twentieth century, the so-called 'miraculous century of physics', has drastically changed our way of life. Th e advent of new physics, the relativity theory and the quantum theory, have dramatically enhanced technology, revolutionizing our vision of the universe. Today, people are in the midst of a new revolution, with our perspective of the world shifted by the concept of 'networks'. Twenty years after the development of low-attenuation single-mode (SM) silica glass optical fi ber (GOF) in the 1970s [1], the United States launched the Information Superhighway project. Th e establishment of a global fiber-optic network has allowed the distribution of a wide range of media content, providing immediate access to new information. Th e world has become much smaller, eliminating physical constraints and endowing people with the ability to connect with anyone at anytime, living anywhere around the world. Th e internet has not only made our life more interesting and livable, but has created new industries, given rise to new cultures, and infl uenced politics. Indeed, it has changed our way of life.However, there remains one final hurdle to achieving ubiquitous high-bandwidth connectivity: there is not yet a high-speed pipeline that connects users to the superhighway. In the 'last hundred meters' between the superhighway and users, especially in home and office local area networks (LANs), optical fi bers must be bent at many points when laid down along walls. However, SM GOF is designed with a small core of just 5-10 μm (Figure 1) so as to excite only one optical mode within the fiber, and is thus not capable of withstanding all the bends required in the last hundred meters. One solution that has been proposed is multi-mode (MM) GOF, which is designed with a larger core. However, the number of modes excited within MM GOF increases dramatically with enlargement of the core region, causing the transmission rate to decrease accordingly due to an increase in the diff erences of the arrival times for each mode (modal dispersion). The future of plastic optical fi berYasuhiro Koike 1,2 * and Makoto Asai 1,3 Keio University, JapanThe number of services providing large-volume information content, such as high-defi nition movies, continues to increase rapidly. Single-mode glass optical fi ber (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 fi bers to signal receiving devices. It is therefore diffi cult 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 fi ber infrastructure. Plastic optical fi ber (POF) has a relatively large-diameter core and is fl exible enough ...
