We propose a fast and accurate estimation method of MDL-induced SNR penalty with non-uniform noise loading in SDM link. The proposed approach substantially saves the time cost while maintaining an estimation error within 0.2 dB.
We propose multi-task learning based NN equalization for nonlinearity compensation in coherent optical system. Compared with conventional NN equalization, 30% complexity reduction is achieved in an 800-Gb/s PDM-16QAM ...

We propose multi-task learning based NN equalization for nonlinearity compensation in coherent optical system. Compared with conventional NN equalization, 30% complexity reduction is achieved in an 800-Gb/s PDM-16QAM system with 5 output symbols.
We propose a flexibly tunable seed source broadening scheme by binarized multi-frequency signal design and high-order phase modulation. Flat-top spectra with different bandwidths up to 20GHz and a 1.5-fold improvement...

Current learning-based computer-generated holography (CGH) algorithms often utilize convolutional neural networks (CNN)-based architectures. However, the CNN-based non-iterative methods mostly underperform the state-o...

Real-time 40×800Gb/s DP-64QAM-PCS transmissions over three different optical fibers (i.e., CTF, G.652.D, G.654.E) are tested under 28-dBm launch power for the first time. No nonlinear penalty is observed in the C...

Combining different forms of prompts with pre-trained large language models has yielded remarkable results on reasoning tasks (e.g. Chain-of-Thought prompting). However, along with testing on more complex reasoning, t...

We design and experimentally demonstrate an efficient fiber-chip edge coupler for NUV using symmetric double-tip taper and MMI-based coupler. We measure the coupling loss down to 2.85 dB at 407 nm on an alumina-on-ins...

We experimentally demonstrate a net 8×250 Gbit/s/λ PAM6 and PAM8 transmission over 200-m standard-125μm-cladding high-density eight-core fiber and low-crosstalk femtosecond laser direct writing fan-in/fan-out d...
We experimentally demonstrate a net 8×250 Gbit/s/λ PAM6 and PAM8 transmission over 200-m standard-125μm-cladding high-density eight-core fiber and low-crosstalk femtosecond laser direct writing fan-in/fan-out devices. The proposed prototype system is promising for high-speed optical interconnection applications.
