    "abstract": "A system for studying microcavity resonators at cryogenic temperatures (~10\nK) through evanescent coupling via optical fiber taper waveguides is reported,\nand efficient fiber coupling to AlGaAs microdisk cavities with embedded quantum\ndots is demonstrated. As an immediate application of this tool, we study\nhigh-resolution tuning of microdisk cavities through nitrogen gas adsorption,\nas first discussed by Mosor, et al. By proper regulation of the nitrogen gas\nflow and delivery of the gas to the sample surface, continuous tuning can be\nachieved with modest gas flows, and overall wavelength shifts as large as 4 nm\nare achieved.",
