Abstract

An optical fiber has a small diameter core (40) for transmitting one or more wavelength multiplexed first light signals in a first direction, and an inner cladding (42) for transmitting a second light signal in the opposite direction. A lower index outer cladding (44) or buffer is used to confine the second signal in the first cladding. The diameter of the core may be less than about ten microns. A notch (30), prism or other suitable device extends into the first cladding (42) and is used to reflect the second signal into an input/output fiber (14). The reflective device (64') may also be used in combination with a multi-function signal generating system mounted on an aimable device. A lens device (18) may be used to collimate the outgoing beam and to converge a reflected return beam onto the end of the first fiber.
