Abstract

PURPOSE: To obtain the photo switching device of less light losses by using polarization plane synthesizing prisms and the crystal having any of electro-optic effect, magneto-optic effect or acousto-optic effect.
CONSTITUTION: The device is constituted by polarization plane synthesizing prisms 5, 7 and the crystal 6 which has any of electro-optic effect, magneto-optic effect or acousto-optic effect and is held applied with any of an electric field, magnetic field or acoustic wave. Input light P1 is separated to a normal ray P10 and abnormal ray PIE by the polariziation plane synthesizing prims 5. While these are passing in the crystal 6, their polarization planes rotate 90° and the polarization plane is changed like normal ray P10→abnormal ray P1E', abnormal ray P1E→normal ray P10'. Hence, the input light P1 is emitted to the output terminal P4 of the polarizing plane synthesizing prims 7. similarly, input light P1 is also changed to normal ray P20→abnormal ray P2E', abnormal ray P2E→normal ray P20' by the crystal 6 and is emitted to the output terminal P3 of the polarization plane synthesizing prims 7. Hence, the optical transmission paths become P1→P4, P2→P3 and are thus switched without any light loss.
