64-Channel WDM Transmitter based on Optical Fourier Transformation using a Portable Time Lens Assembly

We demonstrate 64-WDM-channel generation with 25-GHz spacing from a single SFP+ transceiver using a portable time lens optical processor. After transmission in a 50-km unamplified link, −39.1 dBm average received power sensitivity at
$\text{BER}=10^{-3}$
is measured. © 2022 The Author(s)
