job description

Applications are invited for a postdoctoral research position in high-speed ASIC design for photonic applications. The successful applicant will join a team that designs high-speed ASICs based in the Photonic Systems Group, at the Tyndall National Institute (http://www.tyndall.ie/research/photonics-systems-group/index.html). The high-speed ASICs are targeted towards applications in short-reach optical datacom (development of multilevel transceivers) and optical access networks (advanced burst-mode receivers). In the field of short-reach optical datacom, today there is a strong demand for very high serial link-rates beyond the commercially widely available 10Gb/s solutions, which are based on simple on-off keying. Further increases in line-rate are difficult to achieve due to bandwidth limitations of both electronics and optics. Multilevel modulation formats such as pulse amplitude modulation (M-PAM) are a possible solution; however these require novel drivers and receivers. The research at Tyndall is specifically focused on the implementation of such multilevel transceivers using deep-submicron CMOS technology, with a particular emphasis on ultra low-power consumption. In the field of optical access networks research is now focused on increasing the physical reach of these networks up to 100km and beyond. This requires novel concepts for the burst-mode receiver electronics which are needed to support the time-division multiple access (TDMA) protocols employed in such networks. Tyndall is developing such novel burst-mode receiver technology using SiGe BiCMOS technology.
Description

The position, which is available starting Jan. 2012 for a period of two years, is funded by the Microelectronics Competence Centre Ireland (www.mcci.ie) and Enterprise Ireland. The candidate’s main task will involve the implementation and integration of a 56Gb/s, PAM-4 transceiver for short-reach optical interconnect. In addition, he or she will contribute to the research programme targeting novel burst-mode electronics for the above described long-reach optical access networks. The candidate will also be expected to work closely with the researchers of the Optical Integration Group to facilitate integration of the chips in working modules, as well as with other members of the Photonic Systems Group to facilitate testing of the chips and modules, and their integration into large-scale system test-beds.
