Title:
WAVELENGTH GROUP OPTICAL DEMULTIPLEXER, WAVELENGTH GROUP OPTICAL MULTIPLEXER, AND WAVELENGTH GROUP LIGHT SELECTION SWITCH
Document Type and Number:
WIPO Patent Application WO/2007/123157
Kind Code:
A1
Abstract:
[PROBLEMS] To provide a wavelength group optical multiplexer/demultiplexer
having a simple configuration and capable of separating a wavelength division
multiplexed light into a plurality of preset wavelength groups and outputting
them from a plurality of output ports. [MEANS FOR SOLVING PROBLEMS] A wavelength
division multiplexed light (WDM) can be demultiplexed with a resolution corresponding
to a wavelength channel. An array waveguide grating (AWG) has a characteristic
that when an input port (16) is shifted by one, an output port is shifted by one.
The wavelength division multiplexed light (WDM) is made to pass through the
array waveguide grating (AWG) twice so that a plurality of wavelength groups
(WB) each containing some of the wavelength channels contained in the wavelength
division multiplexed light (WDM) are outputted from a plurality of output ports
(18). Accordingly, it is possible to easily obtain a wavelength group optical
multiplexer/demultiplexer (10) capable of separating a plurality of preset
wavelength groups (WB) from a wavelength division multiplexed light (WDM) formed
by multiplexing a plurality of wavelength groups (WB) each containing a plurality
of wavelength channels and outputting the wavelength groups (WB) from the output
ports (18), respectively.
