Abstract

A high capacity (twelve-channel) fiber optic wavelength demultiplexer incorporating a large diameter GRIN rod lens and grating was developed and fully characterized. The demultiplexer operates over the 740–930-nm wavelength range with an average channel spacing of 17 nm. The insertion loss, measured and averaged over all twelve channels, was ~3 dB, and the average adjacent channel optical cross talk was 32 dB.
