Abstract :
A seven-core optical fiber, each core carrying two wavelength channels, is coupled to a novel silicon photonic integrated circuit (PIC). The silicon PIC uses grating couplers, Mach-Zehnder interferometers, and photodiodes to demultiplex and receive all 14 signals. We demonstrate reception of polarization-scrambled 5-Gb/s on-off keyed signals.
