An Improved Gate Library for Logic Synthesis of Optical Circuits

Optical circuits received increasing interest as an alternative to conventional (i.e. electronic) systems - in particular for ultra-high-speed networks and optical interconnects. Consequently, how to design and synthesize the corresponding circuits became an important EDA problem. But existing solutions relied on a restricted gate library leading to rather expensive circuits. In this work, we introduce an improved gate library by providing optical realizations for many further standard operations such as AND, OR, XOR, etc. By this, synthesis approaches can exploit a broader variety of building blocks and, hence, realize circuits of less costs.
