An electro-optic modulator is disclosed. The electro-optic modulator includes a modulator material film layer. The modulator material film layer includes a polymer matrix. Liquid crystals and getter molecules are dispersed within the polymer matrix. The liquid crystals are configured to modulate light transmissivity through the electro-optic modulator.
