SYSTEMS AND METHODS SIDEBAND HETERODYNING DETECTION

摘要

Systems and methods for sideband heterodyning detection are provided. In certain embodiments a system includes an optical resonator configured to allow light to resonate therein; at least one light source that is controlled to form multiple optical fields, wherein each field is phase or frequency modulated at a common modulation frequency and is at a different frequency. The system also comprises multiple heterodyne modulators that phase or frequency modulate a respective field in the multiple fields at a respective heterodyne frequency to form multiple sidebands, wherein the corresponding heterodyne frequency is different for each heterodyne modulator; at least one coupler that couples the multiple sidebands into the optical resonator; and a feedback control that is configured to detect the multiple sidebands transmitted out of the resonator to create multiple detected sideband signals and adjust frequencies of the plurality of fields based on the multiple detected sideband signals.
