摘要：
We report on an effective means of suppressing polarization dependence in the design of an arrayed waveguide grating (AWG) made of photodefinable polyimide. The polarization dependence of the arrayed-waveguide grating device is excellently suppressed by controlling the grating order (m) for a given refractive index difference between TE-and TM-modes within polyimide. The transmission characteristics of two AWG's for two grating orders, m = 70 and 90, show wavelength shift of 5.04 nm and nearly zero, respectively, strongly supporting and confirming the method that we have identified for the birefringence suppression.
