Paper Abstract

While optical fibers were initially used almost exclusively for point-to-point long haul communications, there is an increasing tendency for fiber to be used in short distance, multi-node configurations. Applications include cable television distribution, subscriber telephone services, high speed data buses, local area and multipoint sensor systems. In these cases the system cost becomes highly dependent on the price of passive branching elements and on splice/connector cost. In addition, there is an increasing requirement for special optical circuits for sensors used in industrial, aeronautical and military systems. Integrated optics offers the possibility of integration coupled with mass production batch methods. While many single-mode integrated optic technologies exist', almost all are incapable of producing waveguides sufficiently large and with an appropriate numerical aperture to couple efficiently to multimode fibers. Ion-exchange in glass can address these shortcomings and thereby has the advantage of being compatible with both single-mode and multimode needs.
