中文摘要	this paper reports that a two-dimensional single-defect photonic crystal waveguide in the f-k direction with triangular lattice on a silicon-on-insulator substrate is fabricated by the combination of electron beam lithography and inductively coupled plasma etching. a ministop band (msb) is observed by the measurement of transmission characteristics. it results from the coupling between the two modes with the same symmetry, which is analysed from the stimulated band diagram by the effective index and the two-dimensional plane wave expansion methods. the parameter working on the msb is the ratio of the radius of air holes to the lattice constant, r/a. it is obtained that the critical r/a value determining the occurrence or disappearance of msb is 0.36. when r/a is larger than or equal to 0.36, the msb occurs. however, when r/a is smaller than 0.36, the msb disappears.
