32. 25Gbps EA-Modulated Widely Tunable V-Cavity Laser Transmitter

Author

Xia, Yimin, Li, Qiaoli, Meng, Jianjun, and He, Jian-Jun

Abstract

We present a widely tunable 25 Gbps transmitter that integrates a V-Cavity Laser and an electro-absorption modulator using an identical epitaxial layer scheme. The transmitter exhibits a wavelength tuning of 41 channels with 100 GHz spacing and a side-mode suppression ratio above 42 dB by varying the TEC temperature by 32 °C. All channels show clear eye diagram openings at a rate of 25 Gbps with a dynamic extinction ratio higher than 9 dB at a fixed peak-to-peak driving voltage of 2 V. Bit-error-rate measurements demonstrate a power penalty less than 3 dB for transmission through 10 km of standard single-mode fiber. This tunable transmitter offers a cost-effective solution that is suitable for use in DWDM access networks.

Abstract

This paper focuses on the dynamic characteristics of wheel–rail collision vibration for high-speed train under crosswind. The wind load model is established by using fast Fourier transform harmonic synthesis method and Davenport coherence function, the lateral displacement of wheelset of high-speed train under crosswind is calculated, the dynamic model of wheel–rail collision vibration system of high-speed train under crosswind is established. The effects of vibration frequency, wheel–rail clearance and lateral damping on the characteristics of wheel–rail lateral clearance impact vibration system of high-speed train are discussed. Numerical simulation results show that the impact velocity of wheelset collision on left and right rails increases with the increase of vibration frequency. When ω > 3.3, the system changes from chaos state to single period stable state through inverse doubling bifurcation; when b < 0.0033, it is in a chaos state, and with the increase of b, the inverse doubling bifurcation occurs until the hunting motion of the wheel–rail system is in a stable state; when ζ ≤ 0.1 , the system is in a stable single period operation state, and with the continuous increase of ζ , it begins to have hop bifurcation, enters a multi-period and chaos state, and finally it is in a stable single period operation state.

Abstract

A decade ago, a group of researchers from academia and industry identified a dichotomy between the industrial and academic state-of-the-art in upper-limb prosthesis control, a widely used bio-robotics application. They proposed that four key technical challenges, if addressed, could bridge this gap and translate academic research into clinically and commercially viable products. These challenges are unintuitive control schemes, lack of sensory feedback, poor robustness and single sensor modality. Here, we provide a perspective review on the research effort that occurred in the last decade, aiming at addressing these challenges. In addition, we discuss three research areas essential to the recent development in upper-limb prosthetic control research but were not envisioned in the review 10 years ago: deep learning methods, surface electromyogram decomposition and open-source databases. To conclude the review, we provide an outlook into the near future of the research and development in upper-limb prosthetic control and beyond. This is a perspective review of the last ten years of translational research and development efforts in non-invasive neural interfaces and robotics for practical and clinical applications of upper-limb prosthetics.
