We have proposed a novel circuit design with the phase correction waveguides in part of the arrayed waveguides to improve the property of an AWG with a narrow spacing and a large channel count without the additional processes such as a UV trimming method. Employing this novel circuit design, we have successfully demonstrated a flat-top 50GHz-88ch with a low crosstalk experimentally.
