Unlike direct detection, which only measures optical intensity, coherent detection recovers the complete optical field\u2014including amplitude, phase, frequency, and polarization state. How Coherent Detection Works A coherent receiver mixes the incoming optical signal with a local oscillator (LO) laser. The mixed signal [&hellip;]"}
