Abstract:
A coupler/splitter including two neighboring coplanar waveguide portions extending in a same direction, the first portion having a constant cross-section, the second portion having a variable cross-section so that the effective index of the second waveguide portion varies, in the upstream-to-downstream direction, from a first lower value to a second value higher than the effective index of the first portion, in adiabatic coupling conditions.
