Loss reduction of arrayed waveguide grating with mode converters designed by wavefront matching method

Mode converters have been designed that reduce mode transition losses in arrayed waveguide grating (AWG) multi/demultiplexers using the authors' recently proposed wavefront matching method. The designed mode converters are very compact and easy to fabricate. AWGs were fabricated equipped with the authors' mode converters. The loss reduction principle was confirmed experimentally.
