We propose a low-complexity and non-iterative SSBI cancellation algorithm operating at the Nyquist sampling rate employing SSBI decomposition followed by sqrt operation, and experimentally validate it in a 58GBaud 16-...
We propose a generalized carrier assisted differential detection receiver featuring simplest structure of 2×2 optical coupler and 2 single-ended photodiodes. The performance of the designed receiver is comprehens...
We leverage modulator finite extinction ratio-induced residual carrier for transparent digital signal processing in coherent time-frequency-division-multiplexing PON. We experimentally demonstrate flexible data rates ...
