Original Kurzfassung:
The advances in silicon photonics motivate the
consideration of optical circuits as a promising circuit technology.
Recently, synthesis for this kind of circuits received significant attention. However, neither the corresponding function descriptions nor the resulting synthesis approaches explicitly considered how optical circuits actually conduct computations ? eventually leading to circuits of improvable quality. In this work, we present a synthesis flow which has explicitly been developed for this technology. To this end, we introduce and exploit OR-Inverter graphs (OIGs) - a data-structure which is particularly suited for the design of optical circuits. Experimental results confirm the efficacy of the OIG structure and the resulting synthesis approach. Compared to several alternative solutions ? relying on conventional function representations ? the number of gates can be reduced by half or even significantly more than that.
