ABSTRACT:
A method and apparatus for splitting/coupling optical signal(s). A unitary waveguide section having a first lateral dimension perpendicular to a propagation axis of the unitary section is provided. An offset waveguide section is optically coupled to the unitary waveguide section. The offset waveguide section has a second lateral dimension approximately equal to twice the first lateral dimension. Two branching waveguide sections having first ends are optically coupled to the offset section at the first ends.
