This Small Business Innovation Research (SBIR) Phase I project is to develop ultra-high speed detector for terahertz applications. The ever-increasing volume of the information to beTransmitted and processed demands fast communication systems that will have to fulfill a throughput of 1 Tb/s or even 10 Tb/s. This requires more than 100 times improvement of performance over today's fiber optic communication systems, and calls for the development of terahertz or femtosecond technologies. The success of this program will lead to drastic improvement of device performance in response speed, gain, responsivity and detectivity. Phase I of this program is to demonstrate the proof-of-concept.The recent surveys suggest that the communication systems will have to fulfill, a throughput of at least 1 Tb/s or even 10 Tb/s by 2010. This puts a demand for more than 100 times improvement of performance in today's fiber-optic communication systems, and calls for the development of terahertz or femtosecond technologies. The potential applications include, detector of ultra-fast laser pulse, generator and detector of ultra-fast electrical transients, broadband detectors, samplers, demultiplexers, and mixer in multi-gigahertz range, high speed optical switches, etc.

这个小型企业创新研究（SBIR）第一阶段项目是开发用于太赫兹应用的超高速探测器。不断增加的信息量被传输和处理的要求快速通信系统，将必须满足1 Tb/s甚至10 Tb/s的吞吐量。这就要求比目前的光纤通信系统性能提高100倍以上，并要求开发太赫兹或飞秒技术。该计划的成功将导致器件在响应速度、增益、响应度和探测率方面的性能大幅提高。该计划的第一阶段是演示概念验证。最近的调查表明，到2010年，通信系统必须满足至少1 Tb/s甚至10 Tb/s的吞吐量。这就要求将当今的光纤通信系统的性能提高100倍以上，并要求开发太赫兹或飞秒技术。其潜在的应用领域包括：超快激光脉冲探测器、超快电瞬变脉冲发生器和探测器、宽带探测器、多千兆赫范围的采样器、解复用器和混频器、高速光开关等。
