MULTICHANNEL OPTICAL WAVELENGTH-SELECTIVE SWITCH WITH ARRAYED-WAVE-GUIDE GRATING MULTIPLEXER

A novel multichannel optical wavelength selective switch is proposed, which can switch arbitrary wavelength signals between multiple channel s at high speed. It is based on the combination of an arrayed-waveguid e grating multiplexer and an array of optical space-division switches. A 1 x 2 optical wavelength selective switch for two multiplexed signa ls with a 0.7nm wavelength spacing is demonstrated using the silica-gl ass based arrayed-waveguide grating multiplexer and the 1 x 2 laser di ode gate switch.
