Abstract
A bidirectional guided optical router includes an evanescent-field optical coupler having three input ports, three output ports, a first central waveguide, a second lateral waveguide and a third lateral waveguide and an evanescent-field-based optical coupling zone in which the first, second and third waveguides are disposed so as to allow evanescent-field-based coupling between the first central waveguide and either one of the lateral waveguides. The 3×3 optical coupler has a length L of between 3154×Leq and 2×Leq such that an optical beam coupled on the first input port having a power p and propagating on the first waveguide in the forward direction is distributed according to the following distribution: a first secondary beam having a power 90% of p/2 on the second output port, another secondary beam having a same power ≧90% of p/2 on the third output port.
