Abstract

Double-functional (optical and electrical) interferometer was realized using holographic recording of dynamic gratings in the semiconductor crystal of CdTe:V We suggest a new method of the slow-down of light pulses, based on beam coupling and generation of holographic current (sometimes called holographic photo-electromotive force (EMF)) in semiconductor materials. Two types of the nonlinear response is considered: 1) fast one (nanosecond), based on plasma, Drude-Lorentz nonlinearity, related to the electron concentration modulation and 2)based on electro-optic effect (in microsecond). Motivation: improvement of biomedical acousto-photonic imaging, acoustical sensing.
