This Small Business Innovation Research (SBIR) Phase I project will develop a pulse measurement device intended to fully characterize optical pulses used in fiber optic telecommunication systems. Next generation optical networks will use 40 Gbit/s rates requiring pulse widths of less than ~25 picoseconds. At this pulse width, dispersion compensation is required to obtain transmission distances of greater than 25 km. In addition, nonlinear optical effects will complicate system development by adding intensity-dependent dispersion. Optical network designers are anticipating these problems by developing active dispersion compensation. However, a requirement of active dispersion compensation is accurate measurements of pulse intensity and phase within an optical network. Then, corrections to the dispersion compensation can be determined exactly. A pulse characterization device is proposed that will be self-contained, have only one fiberized input, be rugged and easy to use.This technology has commercial potential as a diagnostic for telecommunications research and as a diagnostic for optical network design. As optical networks move beyond the OC-192 standard, active dispersion compensation will be required. This technology can used in research applications and can be part of a feedback mechanism to actively control dispersion in functioning optical networks.

该小型企业创新研究 (SBIR) 第一阶段项目将开发一种脉冲测量设备，旨在全面表征光纤电信系统中使用的光脉冲。 下一代光网络将使用 40 Gbit/s 速率，要求脉冲宽度小于约 25 皮秒。 在此脉冲宽度下，需要色散补偿才能获得大于25公里的传输距离。 此外，非线性光学效应会增加与强度相关的色散，从而使系统开发变得复杂。 光网络设计者通过开发主动色散补偿来预见这些问题。 然而，有源色散补偿的要求是准确测量光网络内的脉冲强度和相位。 然后，可以准确地确定色散补偿的校正。 提出了一种脉冲表征装置，该装置将是独立的、只有一个光纤化输入、坚固且易于使用。该技术作为电信研究的诊断和光网络设计的诊断具有商业潜力。 随着光网络超越 OC-192 标准，将需要主动色散补偿。 该技术可用于研究应用，并且可以成为反馈机制的一部分，以主动控制正常运行的光网络中的色散。
