Introduction
Dielectric bend structures play an important role in a variety of photonic inte-
grated circuits.
Transforming a lossless straight waveguide into a bend structure intro-
duces radiation losses.
Due to the boundedness of speed
of the electromagnetic waves, the
wavefronts associated with the
eigenmodes of the bend wave-
guide are curved.
This curvature of the wavefront
gives rise to radiation away from
the waveguide core.
