Abstract
A mode converter for converting an optical signal from a first propagation mode (e.g., LP.sub.01) to a second propagation mode (e.g., LP.sub.02). The mode converter includes a first waveguide supporting a first mode of propagation. The mode converter also includes a second waveguide supporting a second mode of propagation. The first and second waveguides each having a group index characteristic, wherein the first group index characteristic is matched with the second group index characteristic such that electromagnetic energy propagating through the first waveguide at the first mode couples to the second waveguide at the second mode.
