Optimal design for a flat-top AWG demultiplexer by using a fast calculation method based on a Gaussian beam approximation
2006 (English)In: Optics Communications, ISSN 0030-4018, E-ISSN 1873-0310, Vol. 262, no 2, 175-179 p.Article in journal (Refereed) Published
Passband broadening of an AWG (array waveguide grating) demultiplexer with an MMI (multimode interference) coupler connected at the end of a tapered input waveguide is considered. An explicit formula based on the field propagation of an approximate Hermit-Gaussian beam is used to calculate quickly and reliably the spectral response of the AWG demultiplexer. The widths of the input waveguide, the output waveguides and the MMI coupler are optimized. The optimal design is verified with the experimental measurement.
