Dielectric bend structures play an important role in a variety of photonic inte-
¡ 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.
