摘要: We report on the successful design and fabrication of a polarization-insensitive arrayed waveguide grating (AWG), using solgel-derived silica glass films formed fused-silica substrates. By controlling width making propagation constants polarizations equal, we have found it possible to fabricate solgel-based AWGs. Polarization-insensitive improves cross talk by ∼10 dB in dynamic range.
