Keynote address VII possibility of utilization of evanescent surface-wave for optical interconnection thin hollow cylinderical fiber held in air

Summary form only given. To explore the possibility of utilizing the evanescent surface wave propagating on fibers held in air for the purpose of realizing a fiber structure suited for the high bit-rate optical interconnection, a hollow-core cylindrical thin fiber contains no periodic structure within it is examined numerically. It is shown that the fiber having a group velocity close to the vacuum light speed and a relatively low valued GVD can be realized.
