The observation of high-resolution images of confined modes and photonic bands of planar photonic crystal (PPC) nanocavities fabricated in active InGaAsP material by the use of near-field scanning optical microscopy (NSOM) was reported. The smallest optical cavity modes, which were intentionally produced by fractional edge dislocation high-Q cavity designs were also observed. It was found that NSOM is powerful tool for studying local profiles of confined mode in nanocavities.
