First Demonstration of Monolithic Silicon Photonic Integrated Circuit 32×32 Thin-CLOS AWGR for All-to-All Interconnections

We designed, fabricated, and demonstrated the first monolithic silicon photonic Thin-CLOS AWGR. The fabricated Thin-CLOS has 32 ports and four 16-port silicon nitride AWGRs integrated by compact multilayer waveguide routing. Experimental results show 4 dB insertion loss and -20 dB crosstalk.
