    Abstract

    A wavelength selective, (Pb, La)(Zr, Ti)O 3 (PLZT)-based, arrayed-waveguide grating (AWG) with eight output channels at a spacing of 200GHz is reported. The wavelength channel is selected by controlling the voltages applied to electrodes on the AWG. High-speed wavelength selection was successfully demonstrated with a response time of less than 40ns. The extinction ratio was larger than 13dB, and the 3dB optical bandwidth was 110GHz. The insertion loss was 19dB including a coupling loss of 10dB and a waveguide propagation loss of 3dB.
