Optical Properties of Uniaxial Trigonal Crystals of 3m‾ Point Group Symmetry under an Applied Electric Field along X Principal Axis

Jamshid Nayyer*

Pockels activity in uniaxial trigonal crystals with point group symmetry was investigated under an electric field applied along the X principal axis. As the result, the uniaxial crystal deformed into a biaxial crystal exhibiting three distinct refractive indices. One principal axis was shown to lie approximately along the optical axis. The remaining two principal axes were rotated by approximately 45° in the plane transverse to the optical axis. Under application of the electric field, an X-polarized plane-wave light, rotates as it propagates along the optical axis. The length for 90° rotation was determined. Practical applications are discussed.
