The implementation of what we believe to be the first stored-program digital optical computer is described. The implementation domain consists of lithium niobate directional couplers that are modified to provide optical control and are interconnected with single-mode fiber. The architecture is also the first to employ time-of-flight synchronization. That is, there are no flip-flops used as synchronizing memory elements. Synchronization is achieved by the precise timing of the arrival of… 

Optoelectronic time-of-flight design and the demonstration of an all-optical, stored program, digital computer

The recent demonstration of an all-optical, stored-program, digital computer by our group focused on high-speed optoelectronic design. It was made possible by a new digital design method known as

SPOC-a stored program optical computer

TLDR
The Digital Optical Computing group at the University of Colorado at Boulder have built the world's first stored program optical computer (SPOC), which uses the use of optical fibers and pulses of light instead of wires and electronic signals to demonstrate that predictable signal propagation time could replace flip flops for synchronization.

Optical computing by injection-locked lasers

TLDR
A programmable logic gate is demonstrated using an injection-locked Vertical-Cavity Surface-Emitting Laser and the scheme is based on nonlinearity of normalization operations, which can be used to construct any continuous complex function or operation, Boolean or otherwise.

Optical computing and interconnects

In this chapter a general introduction to optical computing is represented and the advantages of using optics in computing along with some important steps taken towards the implementation of an optical parallel computer are illustrated.

The effect of propagation delay uncertainty on the speed of time-of-flight digital optoelectronic circuits

TLDR
A general model of delay uncertainty is developed and focus on the effect that static and dynamic uncertainty accumulated over circuit paths has on the minimum feasible clock period, and a method for traversing the circuit graph representation of a time-of-flight circuit to compute arrival time uncertainty at each pulse interaction point is presented.
