| Abstract: | An efficient technique is used to flatten the spectral response of an arrayed waveguide grating (AWG) multiplexer. By subtracting an increment from the core width of odd arrayed waveguides and by adding the same increment to that of even arrayed waveguides,a box-like spectral response can be obtained. A 17 × 17 polymer AWG multiplexer with boxlike spectral response has been made using FPE polymer materials. Measured result for the AWG shows that the box-like spectral response has a 3dB bandwidth of 0.476nm, the crosstalk is about or less than -21dB for every output channel,and the insertion loss is 13～15dB. |
