Abstract :
A wavelength selective arrayed-waveguide grating (AWG) with 200 GHz channel spacing was fabricated. Buried (Pb, La)(Zr, Ti)O3 (PLZT) waveguides were used to realize a narrow channel spacing of an AWG. This device can select any channel within the free spectral range (FSR) of 1600 GHz using electro-optic effect. Error-free channel selections were demonstrated, and the power penalties were less than 0.5 dB.
