Ultrahigh index contrast planar polymeric strictly non-blocking1024×1024 cross-connect switch matrix

摘要

We report on the first 1024×1024 switch designed in a planar lightwave circuit. Thisrnlevel of integration is enabled by the ultrahigh refractive index contrast achievable in our polymerrnplatform, which is 30% in buried-channel waveguides. The number of building-block 1×2rnY-branch thermo-optic digital optical switches used to achieve strictly non-blocking functionalityrnis 2,095,104. Our most compact design allows 4 chips to fit on a 6-inch wafer. We presentrnarchitectures, design considerations, and implementation schemes.
