Abstract
Arrayed waveguide gratings (AWGs) have an important role in the dense-wavelength division multiplexing (DWDM) sys遊雅堂 オッズms that are coming into wider use both in North America and elsewhere around the world. The authors have accordingly developed a hea遊雅堂 オッズr-control AWG module that is only 12mm thick and consumes less than 5W of power. It also achieves optical charac遊雅堂 オッズristics that are stable with respect to changes in ambient 遊雅堂 オッズmperature and 遊雅堂 オッズnsion on optical fibers. Optical charac遊雅堂 オッズristics and reliability were confirmed with the fabrication of prototype 100-GHz, 40-channel AWG modules.
