Abstract :
Channel tunability of 10 GHz has been demonstrated in a 40-channel 50-GHz-spaced folded silica-on-silicon arrayed waveguide grating (AWG) multiplexer using quadratic nonlinearity in phosphorous-doped glass and a specially shaped electrode. Such AWG can be stabilized and tuned around ITU grid without power-consuming thermoelectric coolers.
