We showcase a fully on-chip CMOS-fabricated silicon photonic integrated circuit employing bidirectionally pumped microring and polarization splitter-rotators tailored for the generation of broadband (>9 THz), high-fidelity (90–98%) polarization-entangled photons. Spanning optical C+L-band producing over 116 frequency-bin pairs on 38.4-GHz-spaced grid, this source is ideal flex-grid wavelength-multiplexed entanglement distribution in multiuser networks.

Frequency-bin encoding furnishes a compelling pathway for quantum information processing systems compatible with established lightwave infrastructures based on fiber-optic transmission and wavelength-division multiplexing. Yet although significant progress has been realized in proof-of-principle tabletop demonstrations, ranging from arbitrary single-qubit gates to controllable multiphoton interference, challenges scaling frequency-bin processors larger remain. In this Perspective, we highlight recent advances at the intersection of integrated photonics that are fundamentally transforming outlook scalable frequency-based information. Focusing specifically results sources, state manipulation, hyperentanglement, envision possible future which on-chip circuits fulfill critical roles processing, particularly communications networking.
