SBIR Phase I: Terahertz Detector

这个小企业创新研究（SBIR）第一阶段项目是开发用于太赫兹应用的超高速探测器。要传输和处理的信息量不断增加，要求快速通信系统必须满足1tb /s甚至10tb /s的吞吐量。这需要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性能在响应速度、增益、响应性和探测性方面的大幅改进。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，通信系统将必须实现至少1tb /s甚至10tb /s的吞吐量。这就要求将当今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。其潜在的应用包括：超快激光脉冲探测器、超快电瞬态发生器和探测器、宽带探测器、采样器、多兆赫范围的解复用器和混频器、高速光开关等。

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.
