Title:
OPTICAL SIGNAL PROCESSING DEVICE AND OPTICAL SIGNAL PROCESSING METHOD
Document Type and Number:
WIPO Patent Application WO/2017/130941
Kind Code:
A1
Abstract:
An optical signal processing device according to a mode of embodiment of the present invention is provided with: a first polarizing separator which splits received light that has been transmitted thereto and that comprises multiple modulated signals multiplexed at different wavelengths, into an electrical transverse wave component and a magnetic transverse wave component; a reference light generator which generates reference light at multiple wavelengths, corresponding to each of the multiple modulated signals in the received light; a second polarizing separator which splits the reference light into an electrical transverse wave component and a magnetic transverse wave component; a first optical coherent detector which generates in-phase components and quadrature components on the polarization axis at each wavelength, from interference components obtained by combining the electrical transverse wave components of the separated received light and reference light, and causing the same to interfere with one another; and a second optical coherent detector which generates in-phase components and quadrature components on the polarization axis at each wavelength, from interference components obtained by combining the magnetic transverse wave components of the separated received light and reference light, and causing the same to interfere with one another.
