Abstract
A polymeric arrayed waveguide grating (AWG) has been proposed and demonstrated by exploiting the nanoimprint method. A PDMS(polydimethylsiloxane) stamp with device patterns engraved was developed out of a master mold made of quartz glass. The device was fabricated by transferring the pattern in the PDMS stamp to a spin-coated polymer film without using any etching process. The device had 8 output channels, while the center wavelengths of each output channel were positioned from 1543.7 nm to 1548.3 nm with the spacing of 0.8 nm. The achieved average channel crosstalk and the 3-dB bandwidth were about 10 dB and 0.8 nm respectively.
