Abstract
Optical add/drop multiplexers (OADM) based on asymmetric y-branches and tilted gratings can be easily fabricated using ion exchange techniques and photosensitive glasses. These devices offer excellent operating characteristics. However, optimum OADM performance depends critically on the angle of the tilted grating. In this paper, results from fabrication and modeling are compared for the ion exchange process using four different angles of the tilted grating. The transmission spectra for the fabricated and simulated OADMs show an excellent agreement.
