0334813HayatThe goal of this collaborative program is to develop high-speed, ultra-low-noise avalanche photodiodes (APDs) for high-capacity fiber optic communication links. The program will have two main thrusts: (1) a theoretical and simulation effort to design and optimize the high-performance APDs and (2) an experimental program to fabricate, characterize, and distribute the APDs. Commercially-available APDs have been widely deployed in 2.5 GB/s optical receivers but have not achieved the anticipated performance advantage at 10 GB/s and it appears unequivocal that they will not be adequate for future 40 GB/s systems. The PIs propose to significantly improve APD performance by introducing new structures and materials based on APD technologies that have recently been developed by the PIs. These include (1) the development of evanescently coupled waveguide structures and (2) the incorporation of optimized impact-ionization engineered multiplication regions. The availability of high-performance APD receivers at 40GB/s as well as 3 to 5 dB improvements in the sensitivity of 10GB/s receivers will have a momentous impact on high-capacity optical transmission systems.An important feature of the program is the development of human resources who will be trained to work in this critically important field. The students who work on this project will become experts in their particular area and will gain extensive understanding in the field of optoelectronics. Of particular note, one of the participating institutions, the University of New Mexico (UNM) is a minority-serving institution (40% of the undergraduate students belong to minority groups including members of several Indian tribes), which gives the PIs the opportunity to recruit undergraduate and graduate students from a pool of under-represented groups. The PIs continue to bring into the classroom relevant elements of their research experience. Both of the PIs' institutions have been actively involved in and advocating web-enhanced instruction.

0334813Hayat 该合作计划的目标是开发用于高容量光纤通信链路的高速、超低噪声雪崩光电二极管（APD）。该计划将有两个主要重点：(1) 设计和优化高性能 APD 的理论和模拟工作；(2) 制造、表征和分发 APD 的实验程序。商用 APD 已广泛部署在 2.5 GB/s 光接收器中，但在 10 GB/s 下尚未实现预期的性能优势，并且显然它们不足以满足未来 40 GB/s 系统的需求。 PI 提议通过引入基于 PI 最近开发的 APD 技术的新结构和材料来显着提高 APD 性能。其中包括（1）渐逝耦合波导结构的开发和（2）优化碰撞电离工程倍增区域的结合。 40GB/s 高性能 APD 接收器的可用性以及 10GB/s 接收器灵敏度 3 至 5 dB 的改进将对大容量光传输系统产生重大影响。该计划的一个重要特点是培养人力资源，他们将接受培训以在这一至关重要的领域工作。从事该项目的学生将成为其特定领域的专家，并将获得对光电领域的广泛了解。特别值得注意的是，参与院校之一的新墨西哥大学 (UNM) 是一所为少数族裔服务的院校（40% 的本科生属于少数族裔群体，包括几个印第安部落的成员），这使 PI 有机会从代表性不足的群体中招收本科生和研究生。 PI 继续将他们研究经验的相关内容带入课堂。这两个 PI 机构都积极参与并倡导网络强化教学。
