Summary: 
The 1 4 optical switch array for wavelength division multiplexing system has been demonstrated where four 14 waveguide digital optical switches have been integrated into one chip. Tape fiber is used as the connection between switch modules to avoid an interconnection fiber jungle. The architecture can be adapted to any number of wavelength channels. Redundant optical switch stage for crosstalk rejection has been used to attain a low crosstalk level. Electro-optic switching is used to attain low power consumption indispensable for routing large wavelength channels.
