Quantum well optical tri-state devices.
We demonstrate quantum well tri-state logic devices for possible use in optical bus architectures. These optical devices are analogous to the tri-state devices often used in electronic buses, where each device can be actively on, actively off, or disabled with at most one device on the bus active at a time. We show two methods of generating these tri-state data, one using tri-state quantum well modulators and one using optical tri-state self-electrooptic effect devices, and we demonstrate a simple optical bus consisting of two such devices. Finally, we comment on the limitations on the number of devices that can be connected to a bus of this type.
