S. Kamei et al., Scaling limitation of N x N signal interconnection in uniform-loss and cyclic-frequency arrayed-waveguide grating, ELECTR LETT, 36(18), 2000, pp. 1578-1580
The authors report on investigation of the effect of coherent crosstalk in
a newly fabricated 16 x 16-channel uniform-loss and cyclic-frequency arraye
d-waveguide grating (ULCF-AWG), and its application to a 16 x 16 interconne
ction network. Its low-crosstalk and uniform-loss characteristics is confir
med and the potential for 48 x 48-channel interconnection is demonstrated.
