Description
Frequency dependent squeezing can achieve quantum noise reduction across the entire detection bandwidth by rotating the squeezed noise ellipse to match the detector response. However, the rotation must be carefully matched to the main interferometer quantum noise curve, which means that the filter cavity detuning and bandwidth must be carefully set according to the SQL frequency. The high optical power proposed for 3G detectors will make operating at the design power difficult. Tunable bandwidth filter cavities offer a promising means to keep the squeezing rotation properly matched throughout the progress of detector development. We report on using an etalon tunable input mirror in the TAMA FDS experiment.
