Abstract :
A multichannel optical wavelength selective switch is investigated, which can switch signals at arbitrary wavelengths between multichannels in wavelength division multiplexing systems. It is based on the combination of an arrayed-waveguide grating (AWG) multiplexer and an array of optical space-division switches. A monolithically integrated 2×2 optical wavelength selective switch is successfully fabricated for four multiplexed signals in the 1.55 μm wavelength region. Here, an AWG and four 2×2 thermooptic switches are laid out on a 30×60 mm2 chip. Wavelength selective switching operations for four wavelength signals between two lines are demonstrated in a time slot of 40 ms with a switching speed of 1 ms
