Abstract
Dense wavelength-division multiplexing is well on its way to dominating the field of fiber-optic communications, and creating the need for higher-capacity multiplexer/demultiplexers for the optical signals. The authors have developed an arrayed waveguide grating (AWG) module that is capable of handling multiple wavelengths and based on planar lightwave circuit (PLC) technology suitable for mass production. Modules are only 8.5mm thick and come in a sealed package. A 100-GHz 16-ch AWG module has been fabricated and has been confirmed to have outstanding optical characteristics and reliability.
