IPC 2017 Acceptance – Kramers-Kronig (KK) receiver


The Kramers-Kronig (KK) receiver, proposed  (https://www.osapublishing.org/optica/abstract.cfm?uri=optica-3-11-1220)  and patented in 2017 with INCIPICT, has been exploited to demonstrate a fiber-optic transmission record: 440 Gb/s on a single channel, single polarization, and with a single photodiode at the receiver. The KK receiver simplifies considerably the receiver design, by only requiring a single photodiode per polarization channel, versus four photodiodes necessary in today’s coherent receivers. The experiment has been carried out in Bell Labs at Crawford Hill (NJ). The unprecedented result has just been presented at the post-deadline session of the IEEE Photonics Conference, in Orlando (https://www.photonicssociety.org/conferences/ieee-photonics-conference).
