Various instruments have been purchased and tested that extend existing nanotechnology capabilities and complement existing equipment. The fact that these laboratories have worked for several years on 3D microcavities and micron-size spectroscopic measurements clarified the need for several complementary instruments. The major new thrust made possible by this grant is spectroscopic capability at 1300 nm. A CCD camera system provides very sensitive detection from 800 to 1600 nm. The existing fs TiSa laser was modified to optimize it for pumping a new optical parametric oscillator, providing short pulses from 1100 to 1600 nm, and the new Millennium X solid state pump provides improved beam stability and efficiency. These instruments have enabled the study of quantum dots and 3D nanocavities, both photonic-crystals and microdisks, in the 1000 - 1300 nm range. A cryostat with nanopositioners within the vacuum has greatly facilitated these measurements, requiring micron stability for minutes. Its temperature control enables scanning of the dot-nanocavity detuning and temperature-dependent measurements.
