All fiber polarimetric modulation using an electro-optic fiber with internal Pb-Sn electrodes.
All fiber electro-optic modulation using a polarimetric cell based on an electro-optic fiber with internal Pb-Sn electrodes was demonstrated. For the polarimetric cell, the electro-optic fiber with two 149 cm long internal electrodes was fabricated by injection of a molten Pb-Sn alloy into the holes of the fiber. The characteristics of the modulation were explained by the electric field induced phase retardation due to the polarization dependent electro-optic Kerr effect. The difference in the effective second order nonlinearity between TM and TE polarization directions was obtained to be 0.0035 pm/V at the applied DC voltage of 6.5 kV.
