Gamma Ray Bursts (GRBs) are the strongest explosions in the universe which might be associated with creation of black holes. Magnetic field structure and burst dynamics may influence polarization of the emitted gamma-rays. Precise polarization detection can be an ultimate tool to unveil the true GRB mechanism. POLAR is a space-borne Compton scattering detector for precise measurements of the GRB polarization...
Based on three-dimensional (3D) Fourier heat flow equation and numerical simulation, we investigated thermal crosstalk of resistive switching memory in 3D crossbar structure for the first time. Our results show that the transient thermal effect will dominate reset process. With the decrease of RS device size, the thermal crosstalk would remarkably deteriorate the retention of RS memory device and...
With the increase of data rate, signal integrity (SI) becomes a bigger challenge for printed circuit board (PCB) designs. Power noise as well as signal loss, inter-symbol interference (ISI), crosstalk needs to be taken into account to ensure a good quality signal design. In this paper, a design case is shared where power noise greatly impacts SATA performance and leads to hard disk (HDD) disconnection...
Novel XPM mitigation technique by coordination of carrier phase recovery and nonlinear polarization crosstalk canceller is proposed. It doubles the Q improvement over conventional method in 112Gb/s DP-QPSK transmission over 1500km SMF link.
An analytical model of XPM induced nonlinear polarization crosstalk is proposed and experimentally verified. Based on this model, various polarization crosstalk mitigation methods including coherent receiver DSP and transmission system design are reviewed.
