Heterogeneous III-V-on-silicon photonic integration has proved to be an attractive and volume manufacturable solution that marries the merits of III-V compounds silicon technology for various integrated circuit (PIC) applications. The current main-stream Ethernet trends larger bandwidth are pushing higher modulation baudrate or employing advanced format datacom However, neither is likely able s...

We examine the correlations between the parameters of ultranarrow off-centred filtering and pulse width on the performance of a wavelength paired Nx40Gbit/s DWDM transmission, consisting of carrier suppressed return-to-zero signal with 0.64 bit/s/Hz (without polarizationdivision multiplexing) spectral efficiency.

A scheme for generating multiwavelength laser source based on a linear optical amplifier (LOA) is demonstrated for potential applications in dense-wavelength division multiplexing (DWDM) communication systems. The laser output shows up to 80 laser lines (SNR at least 20 dB) with 0.4 nm channel spacing covering C and L band. Simultaneous tuning of muti-wavelengths is also demonstrated.

The power of a group DWDM signal increases nonlinear interference in the optical path, especially value FWM. These interfering factors degrade transmission quality and can completely disable WDM system. Therefore, when designing system, it is necessary to optimize transmitted minimize probability error channel. article presents research results analysis affecting fiber-optic communication syste...

With the explosive growth in the Internet traffic in recent years, capacity expansion of dense wavelength-division multiplexing (DWDM) systems is advancing, creating a need for implementation of flexible networks that can reconfigure themselves depending on traffic situations, and for cost reduction. For this reason, conventional distribution feedback (DFB) lasers with fixed wavelengths are rap...
