Abstract :
WDM signal interconnection based on wavelength path routing will be the key technology for the next generation of networks. The Nx N arrayed-waveguide grating (AWG) is one of the most promising devices for this purpose. However, it was not possible to realize full-mesh connectivity because of the substantial pass wavelength non-uniformity and insertion loss imbalance in conventional N x N AWGs. To overcome this problem, we have developed a uniform-loss cyclic-frequency AWG (ULCF-AWG). In this paper, we describe a 32 x 32 ULCF-AWG based metro-scale full-mesh network
