描述了太比特每秒规模的光电连接到硅超大规模集成电路的实验操作。光电纵横开关形式的演示系统已被构建为技术测试台。报告了构成该系统的组件的组装和测试，包括倒装芯片 InGaAs-GaAs 光学接口芯片。使用电子交换芯片的光学输入，以 250 Mb/s 的设计速率（无内部扇出）实现了通过系统的单通道数据路由。凭借 4000 个光输入，这相当于每秒 1 太比特的潜在聚合数据输入到单个 14.6/spl 倍/15.6 毫米 CMOS 芯片中。此外，还利用系统中包含的完整内部光学扇出来切换 50 Mb/s 数据速率，以完成所需的连接。这种跨芯片的同步数据输入相当于 0.2 Tb/s 的聚合数据输入。该实验系统还利用了 CMOS 芯片上时钟信号的光学分布。
The experimental operation of a terabit-per-second scale optoelectronic connection to a silicon very-large-scale-integrated circuit is described. A demonstrator system, in the form of an optoelectronic crossbar switch, has been constructed as a technology test bed. The assembly and testing of the components making up the system, including a flip-chipped InGaAs-GaAs optical interface chip, are reported. Using optical inputs to the electronic switching chip, single-channel routing of data through the system at the design rate of 250 Mb/s (without internal fan-out) was achieved. With 4000 optical inputs, this corresponds to a potential aggregate data input of a terabit per second into the single 14.6 /spl times/ 15.6 mm CMOS chip. In addition 50-Mb/s data rates were switched utilizing the full internal optical fan-out included in the system to complete the required connectivity. This simultaneous input of data across the chip corresponds to an aggregate data input of 0.2 Tb/s. The experimental system also utilized optical distribution of clock signals across the CMOS chip.
