Optically-induced linear electro-optics in Hg-1201 films
The photo-induced linear electro-optics effect (EOE) has been revealed in Hg0.89Pb0.17Ba0.11Ba2CuO4+ (Hg-1201) single crystalline films coated on an MgO surface. Investigations have been performed using time-resolved measurements of the photovoltage, photocurrent, photoresistivity and linear EOE. A time delay shift between the non-linear optical response and photocurrent has been found. Applying external static magnetic fields (up to 1.7 T) we achieve a substantial decrease of the linear electro-optics coefficients. We discuss the possible origin of the observed phenomenon.
