My primary research focus is the reduction of quantum noise in opto-mechanical systems across a broad frequency range. To achieve this, I have developed a novel noise-cancelling device that recreates opto-mechanical interactions using an all-optical approach. This device utilizes two-mode squeezing, a form of quantum entanglement, in conjunction with a beam-splitting process within a polarization-based coupled-cavity topology, generating a tailored frequency-dependent squeezed state. Several key electronic, mechanical, and optical subsystems have been established to support this work, and ongoing efforts are focused on refining the technology to push the boundaries of quantum noise reduction. In parallel, other squeezing experiments are being explored to investigate the properties and applications of squeezed states.
