Abstract

A free-space optical bus system is described for board-to-board interconnections at the backplane level. The system uses active optoelectronic modules as the interface between the circuit boards and the electrical backplane. Substrate-mode holograms are used to implement signal broadcast operations between boards, and each board on the backplane shares common free-space channels for transmitting and receiving signals. System-design considerations are given, and the potential performance of the optical bus system is evaluated. An experimental demonstration is also presented for the signal broadcast operation through cascaded substrate-mode holograms at a data rate of 622 Mb/s.

摘要

本文描述了一种用于背板级板对板互连的自由空间光总线系统。该系统使用有源光电模块作为电路板与电气背板之间的接口。衬底模式全息图用于实现板间信号广播操作，背板上的每个板共享公共自由空间通道来发送和接收信号。文中给出了系统设计考虑因素，并评估了光总线系统的潜在性能。还展示了一个实验演示，通过级联衬底模式全息图以622 Mb/s的数据速率进行信号广播操作。
