A described system includes a first nonlinear element, a filter, and second nonlinear elements. The first nonlinear element can produce, based on an input signal and a first continuous wave (CW) signal, a first output signal that includes the input signal and a phase conjugate copy of the input signal. The filter can produce a filtered signal based on the first output signal and can be programmable to adjust an induced delay between the input signal and the phase conjugate signal. The second nonlinear elements can produce second output signals based on a second CW signal and differently weighted combinations of signal components within the filtered signal. The second output signals can include an in-phase output signal based on an in-phase version of the filtered signal and a quadrature output signal based on a quadrature version of the filtered signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Automatically locked homodyne detection","description":"Systems and techniques relating to automatically-locked homodyne detection are described.
