Abstract

Double-functional (optical and electrical) interferometer was realized using holographic recording of dynamic gratings in the semiconductor crystal of CdTe:V. Two mechanisms of holographic phase grating recording is considered: electro-optic effect (relatively slow, in microsecond) and free-carrier gratings {Drude-Lorentz nonlinearity, fast response in nanoseconds). Both, electrical and optical signals from electro-optic gratings were strong enough to make direct registration on oscilloscope (without preamplifiers) using infrared (IR) CW (λ = 1064 nm) diode pumped 100 mW laser. Step-like phase modulation mimics the pulsed ultrasound modulation, used in biomedical acoustophotonic imaging. Theoretical approach is in agreement with experimental results.
