Document Type and Number:
Japanese Patent JP4276188
Kind Code:
B2
Abstract:
The present invention discloses an art for eliminating the dependency of the optical modulator on the polarization degree by using an orthogonal mode light which is a mixture of two lights that are perpendicular to each other in polarization direction as a light source. An optical communication system of the present invention comprises: a first optical generator and a second optical generator for generating a first single mode light and a second single mode light, respectively, wherein the first single mode light and the second single mode light are orthogonal and non-interfering with each other, and have the same wavelength; a mixing means for mixing the first single mode light and the second single mode light to output an orthogonal mode light; and an optical modulator for amplifying and modulating the orthogonal mode light after receiving the orthogonal mode light through an optical fiber so as to produce a constantly amplified optical signal regardless of a deflection degree of the orthogonal mode light.
