Реферат: LIGHTGUIDE ACCESS PORT Abstract An access port assembly for a main lightwave transmission fiber 16 is made by machining a notch into it by carbon dioxide laser nibbling to form notch faces which extend into the core region. The end face of a second, receiving fiber is placed in contact with the notch faces to optically couple it to the core of the main fiber. An optical epoxy cement holds the two members in position and matches the index of refraction. A third, transmitting fiber is similarly connected to the main fiber in a second notch and perpendicular to the receiving fiber.
