D. Labilloy et al., Finely resolved transmission spectra and band structure of two-dimensionalphotonic crystals using emission from InAs quantum dots, PHYS REV B, 59(3), 1999, pp. 1649-1652
We present continuous near-infared transmission measurements of two-dimensi
onal photonic crystals etched through a (Ga,Al)As waveguide. We use photolu
minescence 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 oscilla
tions around it. This fine structure is exploited to assess the fabrication
parameters and to determine the band structure of the photonic crystal. [S
