  We report a study of the quantum dot emission in short photonic crystal
waveguides. We observe that the quantum dot photoluminescence intensity and
decay rate are strongly enhanced when the emission energy is in resonance with
Fabry-Perot cavity modes in the slow-light regime of the dispersion curve. The
experimental results are in agreement with previous theoretical predictions and
further supported by three-dimensional finite element simulation. Our results
show that the combination of slow group velocity and Fabry-Perot cavity
resonance provides an avenue to efficiently channel photons from quantum dots
into waveguides for integrated quantum photonic applications.
