Demonstration of integrated 12 × 12 InGaAsP/InPgratingwavelength router at 2.5 Gbit/s channel bit rates

Abstract

The authors present a 12 channel InGaAsP/InP wavelength selective router which operates at 2.5 Gbit/s channel rates and uses a slab waveguide based transmission grating. Insertion losses of 7.7 dB and crosstalk levels of –25 dB are measured.
