提出了一种新颖的双单边带信号检测方案。检测可以通过一个具有电缓冲操作的光学零差接收器来执行,该电缓冲操作在不使用光学滤波器的情况下对下边带(LSB)和上边带(USB)信号进行解复用。通过对50 km和100 km标准单模光纤(SSMF)传输的数值模拟,研究了该方案的色散容限特性,并与双边带(DSB)调制进行了比较。双SSB信号的光调制使用双偏振正交相移键控(DP-QPSK)调制器来执行。
: We propose a novel detection scheme for an optical twin single-sideband (twin-SSB) signal. The detection can be performed by one optical homodyne receiver with an electric butter fl y operation which demultiplexes the lower side-band (LSB) and upper side-band (USB) signals without using optical fi lters. The dispersion-tolerant characteristics of the scheme were investigated by numerical simulation of transmission through 50 km and 100 km standard single-mode fi ber (SSMF), in comparison with dual sideband (DSB) modulation. The optical modulation of the twin-SSB signal was performed using a dual polarization quadrature phase shift keying (DP-QPSK) modulator.
