Abstract
We show that a channel waveguide in a two-dimensional photonic crystal chan nel can be considered as a periodic one-dimensional system. Waveguides were fabricated into a GaAs/AlxGa1-xAs waveguide heterostructure and the wavegu ide transmission was measured by detecting the guided photoluminescence of embedded InAs quantum dots excited near the guide entrance. Mini-stopbands related to anticrossings in the dispersion were observed and the spectral l ocation and width of these transmission stopbands is found to agree well wi th calculated values.
