Performance limits of spectro-temporal unitary transformations for coherent modulation
Callum Deakin, Xi Chen
We analyse the performance limits of coherent modulation based on lossless unitary transformations, demonstrating that they can achieve high (30~dB) SINAD and outperform convent…

2.4-THz Bandwidth Optical Coherent Receiver Based on a Photonic Crystal Microcomb
Callum Deakin, Jizhao Zang, Xi Chen +5
We demonstrate a spectrally-sliced single-polarization optical coherent receiver with a record 2.4-THz bandwidth, using a 200-GHz tantalum pentoxide photonic crystal microring reso…
