N. Antoniades et al., A PARAMETRIC WAVELENGTH INTERCHANGING CROSS-CONNECT (WIXC) ARCHITECTURE, IEEE photonics technology letters, 8(10), 1996, pp. 1382-1384
This letter presents an architecture for a wavelength interchanging cr
oss-connect (WIXC) using parametric wavelength converters, The archite
cture exploits the unique properties of the difference frequency gener
ating (DFG) parametric wavelength converter, including its transparenc
y to signal format and its ability to convert multiple wavelengths sim
ultaneously, The WIXC is shown to be scalable and rearrangeably nonblo
cking, Furthermore, connection setup is performed bg the well-known lo
oping algorithm used for Benes networks.
