insights into silicon photonics mach zehnder based Optical Transmitter architectures
IEEE Journal of Solid-state Circuits, 2016Co-Authors: Enrico Temporiti, Andrea Ghilioni, Gabriele Minoia, Piero Orlandi, Matteo Repossi, Daniele Baldi, F SveltoAbstract:Mach–Zehnder-based modulator architectures lend themselves to the realization of high-data-rate Silicon Photonics Transmitters. In this work the challenges set by the integration of such devices on silicon are analyzed in depth. The two main alternative electronic driver architectures, namely multistage and travelling wave, are compared with focus to power efficiency. This is, in fact, a key parameter when considering the stringent requirements of standard module form factors. A 25 Gbps multistage and a 56 Gbps travelling wave modulator have been realized. Each electro-Optical Transmitter is obtained by the 3D assembly of an electronic IC on top of a photonic IC through copper pillars. STMicroelectronics PIC25G Silicon Photonics platform has been adopted for the fabrication of Optical devices, while 65 nm CMOS and 55 nm BiCMOS technologies are exploited to realize the electronic drivers. A 30% better power efficiency compared to Silicon Photonics state-of-the-art at similar data rates and comparable extinction ratio performance has been demonstrated in both cases. Since packaging is also a crucial aspect for Silicon Photonics high volume production, experiments on bare dice as well as on packaged chips are reported.

an fpga based Optical Transmitter design using real time dsp for advanced signal formats and electronic predistortion
Journal of Lightwave Technology, 2007Co-Authors: P M Watts, R Waegemans, Madeleine Glick, P Bayvel, R I KilleyAbstract:Advances in the performance and flexibility of future Optical networks will be brought about through the use of high-speed digital signal processing (DSP) for the generation of advanced Optical signal formats and the compensation of transmission impairments. The use of field-programmable gate arrays (FPGAs) to implement experimental transceivers employing novel DSP techniques is attractive, as they are of low cost and are reprogrammable. In this paper, the design of a reprogrammable FPGA-based 10-Gb/s Optical Transmitter using real-time DSP is described and assessed through simulation. Using a single Xilinx Virtex-4 FPGA, digital filtering based on lookup tables with up to 12-bit addressing could be implemented. We also present, for the first time, a simulation technique using industry-standard digital design simulation tools (mentor graphics modelsim) in combination with a simulation of analog microwave components, Optical transmission, and bit-error-rate estimation to assess the performance of the full transmission system. This simulation technique is used to demonstrate 10-Gb/s transmission over 550 km of standard single-mode fiber (SSMF) using electronic predistortion (EPD) and the generation of Optical single sideband signals. A proof-of-principle experiment is described in which a single 10.7-Gb/s Mach-Zehnder modulator drive signal with 4-bit amplitude resolution and 1-sample/bit temporal resolution was generated. This was used as the input to Monte Carlo simulations to assess EPD transmission performance over SSMF links of up to 640 km.
