We demonstrate single-wavelength, serial and real-time 100 Gb/s NRZ-OOK transmission over 500 m SSMF with a GeSi EAM implemented on a silicon photonics platform. The device was driven with 2 Vpp without 50 Ω termination, allowing a low-complexity solution for 400 GbE short-reach optical interconnects.
Recent advances in integrated opto-electronic devices and front end circuits have made it possible to efficiently transmit very high data rates over optical links for HPC/datacenter applications. This paper reviews our current progress towards serial 100-Gb/s optical interconnects, with emphasis on electrical duobinary (EDB) modulation.
100 Gbit/s three-level (50 Gbit/s OOK) signals are generated using a silicon-organic hybrid modulator and a BiCMOS duobinary driver IC at a BER of 8.5×10−5(<10−2). We demonstrate dispersion-compensated transmission over 5 km.
We demonstrate the first real-time, serial 100 Gb/s NRZ-OOK transmission with an integrated GeSi EAM implemented on a silicon photonics platform. Transmission over 500m of SSMF and 2 km of dispersion shifted fiber is presented.
The performance evaluation of a multi-channel transmitter that employs an arrayed reflective electroabsorption modulator-based photonic integrated circuit and a low-power driver array in conjunction with a multi-channel receiver incorporating a pin photodiode array and integrated arrayed waveguide grating is reported. Due to their small footprint, low power consumption and potential low cost, these...
The increasing demand for bandwidth fuels the development towards high data rate electrical serial links. These links generally suffer from considerable frequency-dependent loss, introducing the need for equalisation at 10 Gbit/s and higher. Modulation schemes with improved spectral efficiency, with respect to non-retrun to zero (NRZ), combined with feed-forward equalisation (FFE), allow increasing...
This paper presents a new long reach PON (LR-PON) scenario operating at a single carrier of 40-Gbit/s for downstream, as an upgrade option of the LR-PON evolutionary strategy. An electrical 3-level duobinary modulation format was proposed for the 40-Gbit/s downstream transmission. In this paper the required optical signal to noise ratio (OSNR) and optical power budget were investigated based on analytic...
High-speed electronic integrated circuits are essential to the development of new fiber-optic communication systems. Close integration and co-design of photonic and electronic devices are becoming more and more a necessity to realize the best performance trade-offs. This paper presents our most recent results and a brief introduction to our research in recently started EU projects.
We present a multi-channel transmitter that employs an arrayed reflective electroabsorption modulator-based photonic integrated circuit and low-power driver array. Error-free 11.3-Gb/s per channel performance is achieved over 96 km of SSMF, with negligible crosstalk (<1-dB penalty) in multi-channel operation.
Within the scope of our EU FP7 C3PO project, we are developing novel, energy-efficient, colourless photonic technologies for low-cost, next-generation dense wavelength-division-multiplexed metro transport and access networks. The colourless transmitters use reflective arrayed photonic integrated circuits, particularly hybrid reflective electroabsorption modulators, and multi-wavelength laser sources,...
An ultra-low power SiGe BiCMOS IC for driving a 10 channel EAM array at 113 Gb/s is presented for WDM-PON applications. The driver array consumes only 2.2 W or 220 mW per channel, 50% below the state of the art.
