Abstract
The effect of sidelobes on the demultiplexing characteristics of a gra ting-folded directional coupler demultiplexer are investigated. The bi t-error-rate characteristics of the demultiplexed signal is examined, and a power penalty originated from the sidelobe is observed for the g rating-folded directional coupler with conventional uniform grating. A phase-synchronized sampled grating is applied to suppress the sidelob e of a Bragg grating, and power-penalty-free demultiplexing is achieve d in this structure.
