The interference patterns in the transmission spectra of a two-dimensi
onal square photonic lattice calculated by the plane-wave expansion me
thod are compared with its photonic band structure in detail. The effe
ctive refractive indices obtained by both calculations correspond to e
ach other quite well. In addition, aperiodic and singular interference
patterns are found when the incident plane wave excites two eigenmode
s with mutually different wave vectors. (C) 1997 Optical Society of Am
