Integrated Circuits for Wavelength Division De-multiplexing in the Electrical Domain

We propose a new concept for a single-chip multi-channel WDM receiver which can scale toward Tbps operation. The receiver, consisting of a single photonic IC and a single electrical IC, multiplies data detection capacity by the number of electrical subcarrier channels. In a first demonstration, two BPSK-modulated wavelength channels have been successfully demodulated.
