OPTICAL DESIGN ALTERNATIVES: A SURVEY STUDY
Computers have enhanced human life to a great extent. Our daily lives demand solutions to increasingly sophisticated and complex problems, which requires more speed and better performance of computers. Although the development of the Very Large Scale Integration (VLSI) technology with smaller device dimensions and greater complexity and speed but it does not permits the demand of faster and enhanced computers. Because of the advantages of optical transmission over electronic ones most of researches focused on optical circuit design. In the recent few years, many studies were published in this field. In this paper we will review different methods of optical digital design.
