Latest Patents

Apostolopoulos holds a patent for a method titled "Electric field poling of ferroelectric materials." This method involves inducing a periodic variation of nonlinearity in a sample of ferroelectric material. The process includes applying an electrically insulating mask to the surface of the sample, applying an electric field to produce domain inversion, and subsequently removing the electric field to retain non-inverted regions beneath the mask. This technique allows for the engineering of accurate domain periods of submicron dimensions, which can be utilized in the fabrication of planar waveguide devices for nonlinear optical applications. The submicron periods can also be exploited in creating one and two-dimensional photonic band gap devices.
