We propose a large scale Clos structure based optical interconnect by employing cyclic arrayed waveguide grating routers (AWGRs) and novel space switching enabled tunable wavelength converters (SS-TWCs). The 1:2 or 1:4 SS-TWCs expand the scale of the optical interconnect up to 8 times of standard Clos structure while using the same AWGR modules. Experimental results are given to demonstrate the feasibility...
The paper presents an optical circuit switching network architecture and its control and traffic scheduling schemes. This optical switch network is built on a 32×32 AWG and fast wavelength tunable transmitters and is able to support up to 128 interface ports. The feasibility of the architecture is verified through an experimental study. The traffic scheduling scheme takes into account the transmitter...
