170-260 GHz Sub-THz Optical Heterodyne Analog Radio-over-Fiber Link for 6G Wireless System
Amol Delmade, Alison Kearney, Simon Nellen +5
The frequency and phase fluctuations of free-running lasers limit the performance of optical heterodyne sub-THz systems - especially for low subcarrier spacing OFDM signals. Digita…

Generation of Spectrally-Efficient Superchannel Using Optical Frequency Comb Referencing and Active Demultiplexing
Yi Lin, Seán Ó Duill, Frank Smyth +3
We generate multiple optical carriers with ultra-low phase noise, over a useable bandwidth of 160 GHz, from an externally injected gain-switched comb source with exceptional low li…
