A Comb-based Colorless Coherent WDM Transmitter
Di Che, Brian Stern, Kwangwoong Kim +4
We propose a comb-based WDM transmitter capable of modulating independent signals to comb lines without demultiplexing them and prove its concept and potential scalability in a WDM…

Dual-Polarization Phase Retrieval Receiver in Silicon Photonics
Brian Stern, Hanzi Huang, Haoshuo Chen +2
We demonstrate a silicon photonic dual-polarization phase retrieval receiver. The receiver recovers phase from intensity-only measurements without a local oscillator or transmitted…

Silicon Photonic Direct-Detection Phase Retrieval Receiver
Brian Stern, Haoshuo Chen, Kwangwoong Kim +3
We demonstrate a direct-detection phase retrieval receiver based on silicon photonics. The receiver implements strong dispersion and delay lines on a compact chip. We retrieve the…
