Summary form only given. We present novel measurements on the lasing modes in microdisk lasers, which provide comprehensive features on out-coupling of WGMs in far- and near-field regimes. The far-field emission patterns are analyzed in polarization-resolved two-dimensional(2-D) angular distribution measurements in the full half space. The near-field emission patterns are analyzed in spectrally resolved near-field scanning optical microscopy (NSOM). Our microdisk lasers are built on a thin InGaAsP slab waveguide structure high index (n=3.4) with an active layer containing a compressively strained multiple quantum well (QW).
