S. Olivier et al., Mini-stopbands of a one-dimensional system: The channel waveguide in a two-dimensional photonic crystal - art. no. 113311, PHYS REV B, 6311(11), 2001, pp. 3311
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.
