Abstract
We present continuous near-infared transmission measurements of two-dimensional photonic crystals etched through a (Ga,Al)As waveguide. We use photoluminescence of InAs self-organized quantum dots as an internal source with a broad guided spectrum. Transmission spectra exhibit both a marked gap for the TE polarization and a fine structure consisting of transmission oscillations around it. This fine structure is exploited to assess the fabrication parameters and to determine the band structure of the photonic crystal. [S0163-1829(99)01804-4].
