H. Notomi et al., Singlemode transmission within photonic bandgap of width-varied single-line-defect photonic crystal waveguides on SOI substrates, ELECTR LETT, 37(5), 2001, pp. 293-295
It is demonstrated experimentally that a single missing-hole line defect ph
otonic crystal waveguide fabricated on a silicon-on-insulator substrate can
support a single waveguiding mode within the photonic bandgap if the waveg
uide width is properly tuned.
