220-GBd optical coherent waveform generation using temporal unitary transforms

arXiv Physics Thursday 18 June 2026, 01:39 UTC By Callum Deakin, Xi Chen, Di Che 1 min read
Key Points

Announce Type: new Abstract: We use temporal unitary transforms to generate 16-QAM up to 220 GBd using only 50-GHz electrical bandwidth. The technique is theoretically lossless and can generate arbitrary optical waveforms beyond the bandwidth of the constituent modulators.

Our ancient enemy: scientists discover oldest-known plague outbreak Ancient DNA from Siberian burials reveals prehistoric outbreaks struck hunter-gatherers long before the Black Death Scientists have found the oldest known evidence of the plague, which sparked deadly outbreaks dating back about 5,500 years ago – some 200 years earlier than previously thought. The disease has sickened humans for thousands of years and wiped out a significant chunk of Europe’s population in the 14th century...
