Abstract
A novel, to our knowledge, integrated wavelength-division multiplexing–passive optical net demultiplexer that uses an arrayed-waveguide grating and diffractive optical elements is presented. The demultiplexer is used to distribute 1.3-μm wavelength signals and to multiplex an eight-channel wavelength-division multiplexer spectrum at a 1.55-μm wavelength. The device shows high functionality and good optical performance. The measured cross talk was less than −21 dB, and the 3-dB bandwidth was determined to be 97 GHz, which is close to the theoretical value of 93 GHz. Average losses of 4.5 and 8 dB were measured for the 1.3- and the 1.55-μm signals, respectively.
