Frequency-bin qubits get the best of time-bin and dual-rail encodings, but require external modulators and pulse shapers to build arbitrary states. Here, instead, the authors work directly on-chip by controlling the interference of biphoton amplitudes gene ...
We demonstrate soliton Kerr-comb generation in a high-Q silicon nitride microring with 143 GHz free spectral range pumped at 1970 nm. The resulting low noise ultrafast pulse train displays a 422 nm bandwidth, extending up to 2250 nm. ...
Chip -scale optical frequency combs enable the generation of highly -coherent pulsed light at gigahertz-level repetition rates, with potential technological impact ranging from telecommunications to sensing and spectroscopy. In combination with techniques ...
