Precision tests of cosmology using gravitational waves will only be possible with improvements to detector sensitivity. I will discuss our efforts to reduce the amount of coating and seismic noise within the LIGO detectors, which has a direct impact on our ability to measure heavier mass black hole mergers further out into the universe. I will focus on a proposed major upgrade to the LIGO detectors that will use silicon optics cooled to cryogenic temperatures. Additionally, I will discuss ideas for a passive seismic isolation system that uses advances in seismic cloaking technology. These improvements will extend distance measurements on gravitational wave mergers from the local universe out to much higher redshifts.
