Abstract

All-optical logic allows high bit rate computation and fast switching, free from electromagnetic interference. Combinational and sequential logic are considered, the latter having memory which allows feedback structures such as flip-flops from which shift registers for storing binary words are constructed. Optical microring resonators are shown to be capable of implementing logic gates such as NOR and AND and they also exhibit bistabiltiy suitable for construction of 1-bit memories or flip-flops. Further, they can be fabricated in silicon on silicon dioxide using standard CMOS VLSI lithography for future integration with electronic VLSI. Microring resonators are a few microns in diameter, enabling high bit rate computation, in the tens or hundreds of Gbps, and fast picosecond switches and latches. A novel combination of microring resonator gates and microring resonator bistable devices is discussed for an all-optical shift register.
