Abstract :
In this work we show how the dispersion relation of slab-type PhCs can be directly determined both in the radiative and guided mode regimes by means of k-space spectroscopy. Angle-resolved reflectance, attenuated total reflectance and micro-photoluminescence spectroscopy are used to determine several important characteristics like band-edge dispersion, slow-light propagation or far-field intensity distribution in passive as well as in active PhC devices. The results are successfully compared to theoretical calculations based on scattering matrix and guided mode expansion methods.
