摘要
This study demonstrates a novel athermal asymmetric arrayed waveguide grating (AWG), which is composed of polymer waveguides on a polymer substrate. The temperature-dependent wavelength shift of the AWG depends on the refractive indices of the polymer materials and the coefficient of thermal expansion (CTE) of the polymer substrate. The athermalization of the AWG can be realized by the selection of the polymer materials and the structural parameters of the waveguide and the substrate.
