Paper Abstract

We describe the design and performance of a multimode 8- channel, 200 GHz-spaced dense wavelength division demultiplexer using a high order blazed grating. The mean insertion loss of this DEMUX is 1.95 dB. Adjacent crosstalk is measured to be better than -45 dB. The temperature test cycling from 20 to 60 degree(s)C indicates that the wavelength thermal drift is less than 0.00033 nm/ degree(s)C. The device has multi-mode fibers for both input and output, which is good for the optical networks in both metropolitan and local areas. The device is not sensitive to the disturbance of temperature and environment, so no temperature controller is needed.
