N2 - Gravitational wave (GW) science from neutron star collisions allows for testing of fundamental science, but their high frequency GW spectrum is buried in quantum shot noise of current interferometric GW detectors. It was proposed to use an optomechanical filter inside the GW detector signal recycling cavity to reduce the quantum shot noise. However, care must be taken such that the mechanical component of the filter does not introduce extra noise. This thesis investigates the design of appropriate resonators for use in optomechanical filters. Detailed quantum noise analysis of the detector is given, showing sensitivity improvement using designed optomechanical filters.
