Technical limitations to homodyne detection at audio frequencies

McKenzie, Kirk; Gray, Malcolm B.; Lam, Ping Koy; McClelland, David E.


Homodyne detection relies on the beat between a relatively strong local oscillator (LO) field at the carrier frequency and a signal beam with sidebands centered around the carrier frequency. This type of signal detection, or signal readout, is widely used in quantum optics applications and is expected to be used in advanced interferometric gravitational wave detectors. We investigate experimentally the limitations to making such measurements in a laboratory environment at audio frequencies. We...[Show more]
