摘要：

The authors successfully demonstrate a new method, called a multigrating method, for a flattened spectral response. It uses one-focal-point couplers and several interleaved monomode waveguide gratings. It has a bandwidth of 0.94nm at -1dB and of 1.8nm at -20dB. The loss penalty due to channel flattening is only 2.2dB.
