| contents | Gravitational-wave astronomy plays a crucial role in early universe cosmology, dark matter detection, and black-hole merger studies. It is shown here that the heterodyne detection of the gravito-optic effect (employing an enhanced Fabry-Pérot cavity) presents a novel broad band approach to gravitational wave detection, with favorable length and frequency scalings. It is demonstrated that such a device is well suited for detecting gravitational waves generated by the annihilation of bosons around black holes, enabling the exploration of a mass range from \( 2.40 \times 10^{-12} \, \mathrm{eV} \) to \( 4.54 \times 10^{-7} \, \mathrm{eV} \). Furthermore, due to the unique coherent nature of gravitational waves generated by boson annihilation any coherent gravitational waves detected above \( 1.23 \times 10^5 \, \mathrm{Hz} \) may be indicative of the existence of black holes of primordial origin. |
