High-dimensional light field modulation demands precise control over multiple optical parameters, a capability critical for next-generation photonic systems. While liquid crystals offer inherent advantages in dynamic birefringence tuning, existing approaches face fundamental limitations in decoupling interdependent phase responses across polarization states. Here, we demonstrate a conjugate phase encoding paradigm enabling simultaneous manipulation of wavelength-dependent wavefronts, orbital angular momentum (OAM), and polarization states in photoaligned liquid crystal devices.
