Coupled-resonator optical waveguides (CROWs) constructed in photonic crystals (PCs) with Archimedean-like tilings are studied in this article. Although unequivalent sites exist in this kind of PC, the transmission properties of the CROWs constructed in PCs with Archimedean-like tilings are comparable with those constructed in periodic PCs. Because of the special structure property of this kind of PC, there are more waveguide modes in CROW constructed in PCs with Archimedean-like tilings. Furthermore, the group velocity of the transmitted electromagnetic waves in this kind of CROWs is smaller than that in its counterpart constructed in periodic PC.
