ABSTRACT:
An access port, a basic building block for optical devices, is formed by joining the ends of two fibers. Each fiber has a wedge-shaped end portion with two planar sides. One planar side of one end portion is held against one planar side of the other end portion. The other planar side of each end portion controls transmission of light from the first fiber to the second fiber.
Optical devices for monitoring, switching, attenuating or distributing the light transmitted through the first fiber advantageously use the access port.
