An optical modulation method comprises writing in a ferroelectric having a glass transition point at or above the glass transition point, and holding the resultant written state below the glass transition point. Preferably, the ferroelectric is formed in an optical modulation layer set to have an optical thickness capable of providing a multiple reflection state. The multiple reflection state of the optical modulation layer is locally changed at or above the glass transition point by irradiating the optical modulation layer under an electric field with a laser beam to write in the optical modulation layer.
