Abstract: We present a phase-sensitive near-field study of speckle fields from photonic crystals in the presence of disorder. We observe phase singularities (vortices) and analyze their statistical properties and screening effects. The experimental results show a clear polarization dependence, not only in their morphological parameters but also in their spatial distribution. (C) 2010 Optical Society of America
