Lane of parallel through carry in ternary optical adder

At the present 50 to 100 microseconds are necessary for a liquid crystal to change its state from opacity to clarity; 1.14 × 10^-5 microseconds are however proved tobe enough for light to pass through a clarity liquid crystal device. Rooted from this great difference in time, an optical adder was constructed with parallel through carry lanes(PTCL) composed of liquid crystals. Because all carries in PTCL process in parallel, thecarry delay in the ternary optical computer's adder is avoided. Eliminating the carry delayin adder of ternary optical computer by physical means, the PTCL is also applicable forother types of optical adders. Moreover a light diagram of the adder and one PTCLstructure are provided.
