Quantum dot lasers are demonstrated for the first time as Raman pumps for amplification of the 1270nm XG-PON upstream band, enabling support of a 50km trunk fibre with a 46.7dB loss budget, which is higher than the E2 class.
The GALACTICO technology platform combines GaAs modulator technology, Silicon board and Germanium receiver technology with 130nm BiCMOS technology. The paper will review the present status of our work, providing an overview of all technological building blocks and system performance.
The introduction of advanced optical modulation formats for coherent data transmission and multilevel signalling enlarges the transmission capacities but also requires more complex opto-electronic components. The need for cost efficient compact solutions is the main driver for photonic-electronic integration technologies. In the framework of the European Project GALACTICO a new mixed technology platform...
Optically assisted downstream cancellation for wavelength reuse in WDM-PONs is demonstrated, allowing downstream extinction ratios up to 9 dB for symmetrical full-duplex data transmission at 10Gbps with RSOA-based ONUs. PON budgets of ~20dB can be reached.
Potential upgrade paths for developing new generation of transmission and switching systems are presented. Increase of integration scale and density through hybrid and monolithic integration technologies is proposed for realizing miniaturized, cost-effective and power-efficient systems.
A simple method for 40 Gbit/s NRZ header extraction based on envelope detection for optical label switching networks is presented. The scheme is insensitive to packet length and spacing and can be single-chip integrated cost-effectively
This paper presents an experimental performance characterization of all-optical subsystems at 40 Gb/s using interconnected hybrid integrated all-optical semiconductor optical amplifier (SOA) Mach-Zehnder interferometer (MZI) gates and flip-flop prototypes. It was shown that optical gates can be treated as generic switching elements and, when efficiently interconnected, can form larger and more functional...
