The advancement of next-generation fiber-optic transmission requires higher-speed transceivers where cost, footprint and power consumption are critical consideration. Photonic integration provides an effective solution to reduce the cost by integrating diverse optoelectronic devices on chips. In particular, complementary metal–oxide–semiconductor (CMOS)-compatible silicon photonics (SiP) has been considered as a promising platform with high density yield. Since coherent receiver relies local...
We propose and experimentally demonstrate a Tomlinson-Harashima precoding (THP) scheme with the coefficients computed by simulations. It realizes spectrally efficient faster-than-Nyquist (FTN) signaling for quadrature amplitude modulation (QAM) format. In our scheme, of THP precoder are obtained numerical simulations an additive white Gaussian noise (AWGN) channel, in which intersymbol interference (ISI) is induced digital FTN filter. Then, we apply these at transmitter to mitigate...
Complex-valued double-sideband (CV-DSB) direct detection (DD) is a promising solution for high capacity and cost-sensitive data center interconnects, since it can reconstruct the optical field as homodyne coherent receiver while does not require costly local oscillator laser. In carrier-assisted CV-DSB DD system, carrier occupies large proportion of total signal power but bears no information. Reducing to ratio (CSPR) improve information-bearing thus maximize achievable system performance....
