Analysis and design of arrayed waveguide gratings with MMI couplers P. Mu˜noz, D. Pastor and J. Capmany Optical Communications Group and IMCO2 Research Institute, Departamento de Comunicaciones, Universidad Polit´ecnica de Valencia, C/ Camino Vera s/n, 46071, Valencia (SPAIN) pascual@ Abstract: We present an extension of the AWG model and design procedure described in [1] to incorporate multimode interference, MMI, couplers. For the first time to our knowledge, a closed formula for the passing bands bandwidth and crosstal kestimation plots are derived. c 2001 Optical Society of America OCIS codes: (230.7390) Waveguides, planar; (060.4230) Multiplexing; (070.2580) Fourier optics; (070.6110) Spatial filtering; (350.2460) Filters, interference; (230.1150) All-optical devices; (230.1950) Diffractio ngratings References and links 1.
