Abstract:

We show how the grating diffraction properties of a N× N waveguide grating router (WGR) can limit the size of N when the device operates with a unique set of N wavelengths as a strict-sense nonblocking N× N cross connect. We motivate why, for large N, the N optical channels should be chosen equally spaced in wavelength and not in frequency. Two different approaches to increase N are presented. We report on results obtained in a 40×40 and a 80×80 WGR.
