✦ Synopsis

A compact eight-channel flat spectral response arrayed waveguide grating (AWG) multiplexer based on siliconon-insulator (SOI) materials has been fabricated on the planar lightwave circuit (PLC). The 1-dB bandwidth of 48 GHz and 3-dB bandwidth of 69 GHz are obtained for the 100 GHz channel spacing. Not only non-adjacent crosstalk but also adjacent crosstalk are less than À25 dB. The on-chip propagation loss range is from 3.5 to 3.9 dB, and the total device size is 1.5 • 1.0 cm 2 .

## Abstract An efficient technique is proposed to flatten the spectral response of an arrayed waveguide grating (AWG) multiplexer. By subtracting an increment from the length difference of odd arrayed waveguides and by adding the same increment to that of even arrayed waveguides, a boxlike spectral

## Abstract A novel structure of arrayed‐waveguide grating (AWG) multiplexers with a graded‐index free‐propagation region (FPR) used to increase the wavelength pass band is presented. The 1‐dB and 3‐dB wavelength pass bands increase with the increase of the graded‐index FPR length. Flat and broaden
