Abstract
We analyze different methods for controlling positions of guided modes of p lanar photonic-crystal waveguides. Methods based both on rearrangements of holes in the photonic-crystal lattice and on changes of hole sizes are pres ented. The ability to tune frequencies of guided modes within a frequency b andgap is necessary to achieve efficient guiding of light within a waveguid e, as well as to match frequencies of eigenmodes of different photonic-crys tal-based devices for the purpose of good coupling between them. We observe and explain the appearance of acceptor-type modes in donor-type waveguides . (C) 2001 Optical Society of America.
