ABSTRACT:
Techniques are disclosed for optical switching and data control, without the interaction of electronic switching speeds. In one example embodiment, a common cavity optical latch is provided that that can hold an optical state for an extended period of time, and the operation of which is controlled optically. Optical phase control allows optical modal switching to be employed between two common optical cavities, using incident optical signals and the way in which the cavities manipulate the phase within them to lock in one or the other configuration, thereby forming an optical latch. The optical latch is implemented in an integrated fashion, such as in a CMOS environment.
