Simultaneous Generation and Transmission of 60-GHz RF and Baseband Signals Employing Only a Simple Single Electrode MZM
Simultaneous Generation Transmission Baseband Signals Employing Only Simple Single Electrode MZM
2015/7/15
Employing only a simple single electrode MZM, a novel hybrid access network, which is capable of generating and transmitting RF-vector (2.5-Gb/s QPSK at 60GHz) and baseband signals (1.25-Gb/s OOK) sim...
Generation of optical millimeter-wave (mm-wave) signal using a Mach–Zehnder modulator (MZM) based on double-sideband (DSB), single-sideband (SSB), and double-sideband with carrier suppression (DSBCS) ...
提出一种采用并行双电极马赫曾德尔调制器(dual-drive MachZehnder modulator,DD-MZM)实现光学倍频毫米波光载无线(radio over fiber,RoF)通信系统的正交相移键控(quadrature phase shift keying,QPSK)调制方法.在中心站，光波进入并行DD-MZM后分为4路，分别由4个微波信号调相.此光波通过光纤后被送到基站，经光电...
Spectral-efficient OOFDM system using compatible SSB modulation with a simple dual-electrode MZM
Frequency modulation Fiber optics optical communications
2015/6/8
A direct-detection OOFDM transmission is experimentally demonstrated which does not need a guard-band between the carrier and the OFDM sideband. The compatible-SSB modulation is realized through a sin...
Observation of Narrow linewidth Beat Signal for Millimeter Wave Generation using MZM-Based Flat Comb Generator
Modulators Two-wave mixing
2015/6/4
We showed 100 GHz beat signals and estimated the linewidth of the beat signal. 100 GHz-spaced optical modes were extracted from 12.5 GHz-spaced comb signals. The linewidth was narrower than 1 Hz.
Optical trellis-coded modulation with multi-parallel MZM
Optical trellis-coded modulation multi-parallel MZM
2015/7/17
We demonstrated trellis-coded modulation onto 10-Gbaud 16QAM by electro-optic vector digital-to-analogue converter employing multi-parallel MZM and trellis encoder. The signal was demodulated with a d...
Novel 42.65 Gbit/s Dual Gate Asynchronous Digital Optical Regenerator Using a Single MZM
Dual Gate Asynchronous Digital Optical Regenerator Single MZM
2015/7/31
We propose and demonstrate experimentally a 42.65Gbit/s dual-gate asynchronous digital optical regenerator in a novel configuration using a single MZM, with receiver sensitivity penalty of only ~2dB.
50-km SMF transmission of 50-Gb/s 16 QAM generated by quad-parallel MZM
SMF transmission QAM quad-parallel MZM
2015/7/31
We investigated transmission of 50Gb/s 16QAM over 50km SMF. 16QAM was electro-optically synthesized with a quad-parallel MZM; demodulated by off-line digital homodyne employing electric equalizers.
