Coherent optical communications using coherence-cloned Kerr soliton microcombs
Yong Geng, Heng Zhou, Wenwen Cui +6
Dissipative Kerr soliton microcomb has been recognized as a promising on-chip multi-wavelength laser source for fiber optical communications, as its comb lines possess frequency an…
Dispersion independent long-haul photon counting OTDR
Bin Li, Ruiming Zhang, Yong Wang +11
Photon counting optical time-domain reflectometry (PC-OTDR) based on the single photon detection is an effective scheme to attain the high spatial resolution for optical fiber faul…
High Dynamic Range Externally Time-gated Photon Counting Optical Time-domain Reflectometry
Bin Li, Guangwei Deng, Ruiming Zhang +8
Single photon detector (SPD) has a maximum count rate due to its dead time, which results in that the dynamic range of photon counting optical time-domain reflectometry (PC-OTDR) d…
Terabit optical OFDM superchannel transmission via coherent carriers of a hybrid chip-scale soliton frequency comb
Yong Geng, Xiatao Huang, Wenwen Cui +9
We demonstrate seamless channel multiplexing and high bitrate superchannel transmission of coherent optical orthogonal-frequency-division-multiplexing (CO-OFDM) data signals utiliz…
