40-Channel Multi/Demultiplexer with Dynamic Passband Shape Compensation
01 July 2001
We present a planar waveguide multi/demultiplexer that can dynamically and independently control the curvature, tilt, and attenuation of its passband shapes. It can reduce the signal distortion caused by other filters in the network. We demonstrate the distortion reduction on a 40 Gb/s return-to-zero signal.
