As internet traffic continues to increase exponentially due to the explosion of mobile multimedia devices, there is renewed demand for electronic circuits, instrumention and optoelectronic systems that can operate at serial data rates in excess of 50 Gb/s. The most advanced optical transmitters which power the backbone of the internet are limited to data rates of 110-Gb/s per optical carrier, 28-Gb/s data streams, and on simple on-off amplitude and/or phase modulation schemes. The next generation of optical fiber standards operating at 400 Gb/s per carrier will have to employ both higher-level modulation formats such as 16-QAM and OFDM, and higher serial bit streams at 56 Gb/s and 112 Gb/s. Such systems will require revolutionary mixed-signal analog-digital transmitter and receiver architectures. This grant proposes to investigate, design, fabricate, and demonstrate novel analog-to-digital and digital-to-analog converters that would have approximately 4 times larger bandwidth than today's most advanced published research results. They will be world-leading and pave the wave for the next generation of test equipment and of 1 Tb/s optical communication systems. The strong commitment and close collaboration with Ciena's world-leading optical IC communication research and development group in Ottawa will ensure that Canada and Ontario will remain the world leader in high-data rate optical communications. The grant will train a large number of graduate and undergraduate students in high-speed and mm-wave integrated circuits, and in fiberoptic sytems integration. They will carry on the expertise, entrepreneurship, and wealth creation that has characterized this field during the past 20 years at Nortel, Quake Technologies, Ciena, and many other world-class Canadian fiberoptic companies.

随着互联网流量由于移动的多媒体设备的爆炸而继续呈指数级增长，对能够以超过50 Gb/s的串行数据速率操作的电子电路、仪器和光电系统存在新的需求。为互联网骨干网提供动力的最先进的光发射机仅限于每个光载波110 Gb/s的数据速率，28 Gb/s的数据流，以及简单的开关幅度和/或相位调制方案。下一代以每载波400 Gb/s工作的光纤标准将必须采用更高级别的调制格式，如16-QAM和OFDM，以及56 Gb/s和112 Gb/s的更高串行比特流。 这样的系统将需要革命性的混合信号模拟数字发射机和接收机架构。该资助旨在研究、设计、制造和演示新型模数和数模转换器，其带宽约为当今最先进的已发表研究成果的4倍。它们将是世界领先的，并为下一代测试设备和1 Tb/s光通信系统铺平道路。与Ciena位于渥太华的世界领先的光IC通信研发团队的坚定承诺和密切合作将确保加拿大和安大略在高数据速率光通信领域保持世界领先地位。 这笔赠款将培养大量的研究生和本科生在高速和毫米波集成电路，并在光纤系统集成。他们将继续在过去20年中在北电、Quake Technologies、Ciena和许多其他世界级的加拿大光纤公司从事这一领域的专业知识、创业精神和财富创造。
