We demonstrate a silicon photonic transmitter for soliton-based communications enabling
the interleaving of QPSK and APSK modulated soliton pulses overlapping in both the time …

It is shown that a higher spectral efficiency (SE) can be achieved in a narrow-bandwidth-
modulated NFDM subsystem than a moderate-bandwidth one. Exploiting the statistical …

Electrical-optical signal processing has been shown to be a promising path to overcome the
limitations of state-of-the-art all-electrical data converters. In addition to ultra-broadband …

For discrete spectrum modulated nonlinear frequency division multiplexing (DS-NFDM)
transmission, the combined effect of laser frequency offset (FO) and amplifier spontaneous …

We experimentally demonstrated a geometric shaped (GS) 64-ary amplitude phase shift
keying (64-APSK) eigenvalue transmission. The signal is modulated on the scatter …

Nonlinear frequency division multiplexing (NFDM), as a possible technique to overcome the
limit imposed by Kerr nonlinearity in conventional coherent optical communication systems …

We present a fast method to calculate the significantly large solitonic components of signals
with large time-bandwidth products governed by the nonlinear Schrödinger equation, for …

Owing to the random birefringence of optical fibers, the recovery of the state of polarization

Nonlinear frequency division multiplexing (NFDM) is a promising optical transmission
system that avoids fiber nonlinear effects, but suffering from unsatisfied spectral efficiency …
