Abstract: This paper presents the first investigation of a novel method to obtain an apodization effect on common InP ridge waveguide filters. It consists of the use of particular sampled gratings. Such apodized filters measured transmission spectra present an enhanced rejection of about 20 dB of the adjacent sidelobes, which experimentally validate the concept. © 2006 Wiley Periodicals, Inc.
