Abstract
A ring interferometer which has a light waveguide with two ends which act as the two separate coupling points so that light from a source can be coupled into each of the ends to travel in the light waveguide to be uncoupled from the opposite end as an output coupled light traveling in a separate output path characterized by the separate output paths of the output coupled light from the coupling point to a unification point where components are superimposed into a superimposed path directed to the light receiving surface have different lengths and the amount of the difference exceeds the coherence length of the coherent light employed in the ring interferometer.
