Geometrical Representation of the Linear Symmetric Coupler
A Bloch vector model was set up using the light field electric vector in two waveguides of the liner symmetric coupler. The light “transition” process in two waveguide channels was quite directly with the Bloch vector rotation changing. It was found that the more serious the propagation constant mismatches, the faster the frequency of light energy exchanges and the lower efficiency exchanges, which is equal to the results solved by the traditional equations.
