Silicon-based monolithic 4/spl times/4 wavelength-selective cross connect with on-chip micromirrors

A monolithic 4/spl times/4 wavelength-selective cross-connect (chip area = 3.2/spl times/4.6 cm ) is realized by integrating four 4/spl times/1 MEMS wavelength-selective switches and four 1/spl times/4 passive splitters, together with a 4/spl times/4 waveguide shuffle network on a silicon-on-insulator. Wavelength-selective routing has been successfully demonstrated.
