Abstract :
Most of the waveguide grating router´s loss comes from fiber coupling and star coupler. Our three-dimensional (3-D) models quantifies both losses. In addition, we study how various waveguide parameters affect the value and nonuniformity of this loss. Our optimization yields a design where the total fiber-to-fiber insertion loss can be reduced to 0.535 dB
