We present an all-analog phase bias locking scheme where error signals are obtained from the beat between the optical carrier and optical tones generated by an auxiliary 2 MHz 𝑅𝐹 tone to lock the phases of all three involved interferometers for operation up to 10 GHz. With the developed method, we demonstrate an I/Q modulator in carrier-suppressed single-sideband mode, where the suppressed carrier and sideband are locked at optical power levels <−27dB\r\n relative to the transmitted sideband. We describe a simple analytical model for calculating the error signals and detail the implementation of the electronic circuitry for the implementation of the method.","lang":"eng"}],"publication_status":"published","scopus_import":"1","issue":"1","keyword":["Atomic and Molecular Physics","and Optics","Engineering (miscellaneous)","Electrical and Electronic Engineering"]}
