A wavelength selective AWG (arrayed-waveguide grating) was fabricated using buried PLZT ((Pb, La)(Zr, Ti)O ₃) waveguides. It has 8 output channels with 200GHz spacing. The buried PLZT waveguides have lower propagation loss and higher optical confinement compared to the previously reported ridge PLZT waveguides. Therefore, using buried PLZT waveguides, an AWG with shorter channel spacing than a conventional AWG can be designed and fabricated. The 3-dB bandwidth was 110GHz, the maximum control voltage was 14V, and the tuning range was 1600GHz. Wavelength tuning was successfully demonstrated with a crosstalk of about -14dB for TE (transverse electric) polarized light and -13dB for TM (transverse magnetic) polarized light.
