Optical switch using optical fibers
Abstract:
A method and apparatus for routing light signals. A light signal is sent into a first optical fiber core in an optical coupler having an input region, a coupling region, and an output region. The first optical fiber core is located in a cladding having a substantially circular cross section. The light signal is coupled between the first optical fiber core and one of the first optical fiber core and a second optical fiber core in the coupling region of the optical coupler based on a position of the coupling region as the light signal travels through the coupling region to the output region of the optical coupler using a switching system configured to move the coupling region between one of a first position and a second position.
