The application for the patent was published on July 10, 2026, under issue no. 28/2026.
Abstract: ABSTRACT SELF-BALANCING HOMODYNE DETECTORS AND METHODS THEREOF Disclosed herein is a homodyne detector (200) comprising a first beam splitter (202) and a second beam splitter (204) optically coupled with each other via at least an optical modulator 5 (210). The first beam splitter (202) is configured to receive an optical signal and a reference optical signal as input and generate a first optical beam and a second optical beam based on the optical signal and the reference optical signal. The second beam splitter (204) is configured to receive at least the first optical beam through the optical modulator (210). The homodyne detector (200) comprises a control circuit (212) coupled to an output end of an amplifier (110) 10 of the homodyne detector (200) and the optical modulator (210). The control circuit (212) is configured to balance one or more imbalances in the homodyne detector (200) by controlling the first optical beam passing through the optical modulator (210) based on an output signal of the amplifier (110)
