Abstract:
There is provided an integration-type optical modulation device which performs polarization-beam-combining on two linearly polarized light beams respectively output from a plurality of optical modulation elements and outputs the resultant beam so as to seek an improvement and stabilization of optical characteristics, miniaturization, and low cost. The optical modulation device includes: two optical modulation elements ( 120 a  and the like) that respectively output two output light beams; four lenses ( 140 a  and the like) that respectively receive the four output light beams output from the optical modulation elements; a polarization rotation element ( 108 ) that together rotates polarization direction of respective ones of the respective two output light beams output from the two optical modulation elements; and two polarization beam combining elements ( 110 a  and  110 b ) that respectively combine the two output light beams respectively output from the two optical modulation elements into one beam and output the one beam, in which the light beams respectively output from the four lenses are directly input to the polarization rotation element and/or the two polarization beam combining elements without passing through an optical path shift prism.

Claim (Index 1):
An optical modulation device comprising:\n a first optical modulation element and a second optical modulation element each of which outputs two output light beams; four lenses that respectively receive the four output light beams output from the two optical modulation elements; a polarization rotation element that rotates polarization direction of one of the two output light beams from the first optical modulation element and polarization direction of one of the two output light beams from the second optical modulation element; a first polarization beam combining element that combines the two output light beams from the first optical modulation element into one beam and outputs the combined beam; and a second polarization beam combining element that combines the two output light beams from the second optical modulation element into one beam and outputs the combined beam, wherein the light beams respectively output from the four lenses are directly input to the polarization rotation element and/or the first and second polarization beam combining elements without passing through an optical path shift prism.
