Optical circuits received significant interest as apromising alternative to existing electronic systems. Because ofthis, also the synthesis of optical circuits receives increasing atten-tion. However, initial solutions for the synthesis of optical circuitseither rely on manual design or rather straight-forward mappingsfrom established data-structures such as BDDs, SoPs/ESoPs,etc. to the corresponding optical netlist. These approaches hardlyutilize the full potential of the gate libraries available in thisdomain. In this paper, we propose an alternative synthesissolution based onAND-Inverter Graphs(AIGs) which is capableof utilizing this potential. That is, a scheme is presented whichdedicatedly maps the given function representation to the desiredcircuit in a one-to-one fashion – yielding significantly smallercircuit sizes. Experimental evaluations confirm that the proposedsolution generates optical circuits with up to 97% less numberof gates as compared to existing synthesis approaches.
