Enhanced detection of high frequency gravitational waves using optically diluted optomechanical filters

Page, Michael; Qin, Jiayi; La Fontaine, James; Zhao, Chunnong; Ju, Li; Blair, David


Detections of gravitational waves (GW) in the frequency band 35 to 500 Hz have led to the birth of GW astronomy. Expected signals above 500 Hz, such as the quasinormal modes of lower mass black holes and neutron star merger signatures, are currently not detectable due to increasing quantum shot noise at high frequencies. Squeezed vacuum injection has been shown to allow broadband sensitivity improvement, but this technique does not change the slope of the noise at high frequency. It has been...[Show more]
