<P>PROBLEM TO BE SOLVED: To provide a wavelength multiplexing optical transmitter, capable of reducing a non-linear crosstalks and linear crosstalks between optical carriers whose frequencies adjoin. <P>SOLUTION: The transmitter comprises a polarization quadrature multiple-wavelength light source 8 for transmitting a plurality of linearly-polarized wave optical carriers, in which polarized waves among optical carriers whose frequencies are adjacent are orthogonal, and a plurality of injection-synchronized optical transmitters 11<SB>1</SB>to 11<SB>N</SB>, by which a plurality of linearly-polarized wave optical carriers are inputted via a linear polarization maintaining optical coupler 10; each of the plurality of injection-synchronized optical transmitters, 11<SB>1</SB>to 11<SB>N</SB>, synchronizes with any one of frequencies and polarized waves of the plurality of linearly-polarized wave optical carriers, and produces modulated optical signals in each of which the frequency spectrum does not overlap; and the linear polarization maintaining optical coupler 10 outputs a plurality of produced modulated optical signals, after multiplexing. <P>COPYRIGHT: (C)2010,JPO&INPIT |
