Abstract:
A wavelength routing SW is a large-scale optical switch device of a conventional technique, and it requires as many wavelength-tunable light sources as the number of input ports. For the wavelength-tunable light sources to achieve a stable oscillating operation across a wide wavelength range, a complicated control mechanism is necessary. This has been an obstacle in providing a large-scale optical switch device in terms of cost and circuit scale. A wavelength routing SW in the present disclosure includes N wavelength group generators, a splitting-selection unit, and MN tunable filters. Each wavelength group generator includes M fixed-wavelength light sources. Inexpensive general-purpose devices that require no control mechanism for wavelength tuning can be used as the fixed-wavelength light source. The channel loss in the optical switch device can also be reduced by using light sources with a limited narrow range of tunable wavelengths and the wavelength-dependent output port selecting function of an AWG.

Claim (Index 15):
The optical switch device according to  claim 14 , wherein\n the optical switch device further comprises at most M light sources each of which generates a light beam with one wavelength among light beams with the at most M different wavelengths, includes a means for modulating the light beam with an electrical signal, and outputs the modulated light beam with the one wavelength, the at most M light sources and a corresponding one of the N multiplexers constitute a wavelength group generator, and the MN tunable filters each select a modulated light beam with any one wavelength.
