We propose a hardware-efficient single-ended coherent receiver structure using two arbitrary output tributaries of a 3×3 coupler. We experimentally demonstrate 1.008-Tb/s line rate (820-Gb/s net rate) PS-64-QAM signal reception after 80-km standard single-mode fiber transmission.
We experimentally demonstrated line rate 300-Gb/s PAM4 and 400-Gb/s probabilistically shaped (PS)-PAM16 transmission using packaged thin-film LiNbO3 modulators with only 550-mVpp CMOS-class driving voltage requiring n...

We propose a theoretical mechanism and new coding strategy to realize extremely accurate manipulations of nonlinear electromagnetic harmonics in ultrawide frequency band based on a time-domain digital coding metasurface(TDCM).Using the proposed mechanism and coding strategy,we design and fabricate a millimeter-wave(mmWave) TDCM,which is composed of reprogrammable meta-atoms embedded with positive-intrinsic-negative *** controlling the duty ratios and time delays of the digital coding sequences loaded on a TDCM,experimental results show that both amplitudes and phases of different harmonics can be engineered at will simultaneously and precisely in broad frequency band from 22 to33 GHz,even when the coding states are imperfect,which is in good agreement with theoretical *** on the fabricated high-performance TDCM,we further propose and experimentally realize a large-capacity mmWave wireless communicationsystem,where 256 quadrature amplitude modulation,along with other schemes,is *** new wireless communicationsystem has a much simpler architecture than the currently used mmWave wireless systems,and hence can significantly reduce the hardware *** believe that the proposed method and system architecture can find vast application in future mmWave and terahertz-wave wireless communication and radar systems.
Reconfigurable holographic surfaces (RHSs) have been proposed as a cost-effective and power-efficient solution for extremely large-scale arrays, where the amplitude of electromagnetic waves radiated at each element is...
