The wavelength at which the group velocity dispersion crosses zero can be set by varying fibre core diameter or index step. Moreover, sophisticated methods to manipulate higher-order dispersion so as shape and even flatten dispersion over wide bandwidths are possible using multi-cladding fibre. Here we introduce design and fabrication techniques that allow analogous dispersion control in chip-int","authors_text":"Daniel C. Cole, Dong Yoon Oh, Hansuek Lee, Jiang Li, Katja Beha, Kerry J.
