Design and Fabrication of a 400GHz InP-Based Arrayed Waveguide Grating with Flattened Spectral ResponseSupported by the National Natural Science Foundation of China under Grant Nos 61274046, 61201103, 61335009 and 61320106013, and the National Basic Research Program of China under Grant No 2013AA014202

A four-channel 400 GHz channel spacing InP-based arrayed waveguide grating with a flattened wavelength response by employing a multimode interference coupler at the input waveguide of the filter is prepared. The fabricated devices show a flattened spectral response with a broadened 3-dB bandwidth up...

Description
Summary:A four-channel 400 GHz channel spacing InP-based arrayed waveguide grating with a flattened wavelength response by employing a multimode interference coupler at the input waveguide of the filter is prepared. The fabricated devices show a flattened spectral response with a broadened 3-dB bandwidth up to 3.5 nm, interchannel non-uniformity of
