All optical method is considered as a promising technique for high symbol rate Nyquist signal generation, which has attracted a lot of research interests for high spectral-efficiency and high-capacity ...

Spectrum efficient data transmission is of key interest for high capacity optical communication systems considering the limited available bandwidth. Transmission of the high speed signal with ...

Fig 1. A DP-QPSK transmitter and a coherent receiver with ADC and DSP are key analog components for long-distance transmission systems. Fig 2. Shown is the measured (blue, green) and simulated (red) ...

Fig 1. In this view of the architecture of an optical analyzer, the coherent reference receiver serves as the optical front end to the digitizer, taking as inputs two single-mode fibers, one carrying ...

As telecommunication technologies evolve there is an on-going drive for the development of high-performance systems for radio communications. Part of that evolution involves implementing components in ...
