Abstract :
We demonstrate an all-optical wavelength-routing switch monolithically integrated with four wavelength converters and an 8times8 arrayed-waveguide-grating (AWG) filter. In the switch, double-ring-resonator-coupled tunable laser diodes allow rapid and stable switching between output ports (~5 ns) and optical gates based on a parallel amplifier structure prevent the input optical signal from being routed through the AWG (filter-free operation).
