A conceptually novel materials design, based on crosslinked ferroelectric liquid‐crystalline polymers , is demonstrated for efficient switching of a second‐order nonlinear optical (NLO) response in the solid state. By controlling the molecular alignment of the NLO moieties through two‐photon isomerization of azobenzene molecules, reversible isothermal photocontrol of second‐harmonic generation is achieved with contrast of up to 20.
