Paper Abstract

A 2D wavelength-division demultiplexing device is demonstrated to separate and to distribute optical signals of different wavelengths by use of substrate-guided wave optical interconnects. In our experiment, two stacked input holographic gratings are fabricated to steer two optical wavelengths into two different routing directions and to zigzag within a waveguiding substrate. Input coupling efficiencies of 70 percent and 76 percent are experimentally confirmed at the input wavelengths of 780 nm and 790 nm, respectively. Two arrays of 1-to-10 cascaded output holographic grating couplers are employed to couple out the optical signals with surface-normal fanouts. The crosstalk is measured to be < -30 dB. The fanout energy fluctuation is within +/- 10 percent for each wavelength.
