Characteristics of semiconductor optical waveguides fabricated by impurity-induced layer disordering
… induced layer disorder-delineated buried channel optical waveguide non-rectilinear routing structures are found to have loss properties equal to or better than other planar optical waveguides. With 3 dB loss angles of 3$\sp\circ$, for simple abrupt bends, and 7$\sp\circ$, for modified abrupt …
