Abstract

Arrayed waveguide gratings Arrayed waveguide gratings (AWGs) Band pass filters Bandwidth Crosstalk Equations Insertion loss integrated optical devices Mercury (metals) multiplexers Optical losses Optical waveguides Passband wide-band filters
We present the principle of hyper-Gaussian arrayed waveguide grating (AWG), applied successfully to realize an ultraflat 500-GHz spacing demultiplexer with 1-dB passband above 80% of the channel spacing, and a zero chromatic dispersion 50-GHz spacing wide-band AWG.
